    Answer:  The equation, in “slope-intercept form” ; is:

    ________________________________________________

                       →   ” y  =   x  +  4  ” .

    ________________________________________________

    Step-by-step explanation:

    ________________________________________________

    Use the formula for linear equations;  written in “point-slope format” ;

    which is:

          y −  y₁  = m( x −  x₁ )  ;

    We are given the slope, “m” ;  has a value of:  “1 ” ;  

               that is;  “ m = 2 ” .

    ________________________________________________

      We are given the coordinates to 1 (one) point on the line; in which the coordinates are in the form of :

        ” ( x₁ , y₁ ) ” ;  

    →   that given point is:  “(10, 6)” ;  

                in which:  x₁ =  10 ;

                                 y₁  =  6 .

    → Given:  The slope, “m” equals “1” ;  ________________________________________________

    Let’s plug our known values into the formula:

        →  ”  y  −  y₁  = m( x − x₁ ) ”  ;

    _______________________________________________

        →   As follows:

        →   ” y  −  10  = 1(x − 6) ;

    ______________________________________________

    Now, focus on the “right-hand side of the equation” ;

        →    1(x  −  6) = ? ;   Simplify.

    ______________________________________________

    Note the “distributive property” of multiplication:

                →  a(b + c) =  ab   +   ac ;

    As such:  ” 1(x  −  6) =  (1*x)  +  (1 * -6) ” ;

                                 =  1x   + (-6) ;

                                 =   x  −  6 ;

    [Note that:  ” 1 x = 1 * x = x ” ;

    [Note that   ” + (-6) ”  =  ” ( ” − 6 ” ) .] ;  

                     →  {since:  “Adding a negative” is the same as:

                                      “subtracting a positive.”} ;

    ________________________________________________

              Now, let us bring down the “left-hand side of the equation” ; &

    rewrite the entire equation; as follows:

    ________________________________________________

                               →   ”  y  −  10  =   x  −  6 ” ;  

    ________________________________________________

    Note:  We want to rewrite the equation in “slope-intercept form” ;

               that is;  “ y = mx + b ”  ;

                     in which:  “y” ; stands alone as a single variable on the “left-hand side” of the equation;  with “no coefficients” [except for the “implied coefficient” of ” 1 “} ;

                                     “m” is the coefficient of “x” ;

                                     and the “slope of the line” ;  

              Note that “m” may be a “fraction or decimal” ; and may be “positive or negative.

                If the slope is “1” ; (that is “1 over 1″ ; or: “\frac1}{1}” ;

    then,  “ m = 1 ” ;  and we can write ” 1x ” as simply “x” ; since the implied coefficient is1” ;  

                   →  since ” 1” , multiplied by any value {in our case, any value for “x”} , equals that same value.

    ________________________________________________

           “b”  refers to the “y-intercept” of the graph of the equation;  

               that is; the “y-value” of the point at which the graphed line of the equation crosses the “y-axis” ;  

               that is, the “y-value” of the coordinates of the point at which the graphed line of the equation crosses the “y-axis” ;

               that is, the [“y-value” of the]  y-intercept” .  

    Note that the value of “b” may be positive or negative, and may be a decimal or fraction.

      If the value for “b” is negative, the equation can be written in the form:

              ” y = mx – b ” ;

        {since:  ” y = mx + (-b) ”  is a bit tedious .}

              If the y-intercept is “0” ; (i.e. the line crosses the y-axis at the origin, at point:  ” (0,0) ” ;  

    then we simply write the equation as:  “y = mx ” ;  

                                    ________________________________________________

    So;  we have:              →   ” y   10  =  x  −  6 ” ;  

    ________________________________________________

           →   We want to rewrite our equation in slope-intercept form,

    that is;  ” y = mx + b ” ;  as explained above.

     

    We can add “10” to each side of the equation ; to isolation the “y” on the “left-hand side” of the equation:

               →  ” y  −  10  + 10  =  x  − 6  +  10 ” ;

    to get:

               →  ” y  =  x  +  4 ” ;

    ________________________________________________

              →  which is our answer.

    ________________________________________________

    Note:  This answer:  ” y = x + 4 ” ;

                      →  is written in the “slope-intercept format”;  

                         →   “ y = mx +  b ”  ;

      in which:  “y” is isolated as a single variable on the “left-hand side of the equation” ;

                       The slope of the equation is “1” ; or an implied value of “1” ;

        that is;   ” m  = 1 ” ;  

                       “b  =  4 ” ;  

             →  {that is;  the “y-value” of the  “y-intercept” —  “(0, 4)” — of the graph of the equation is:  “4 “.} .
