    Slope-intercept form: y = mx + b

    (m is the slope, b is the y-intercept or the y value when x = 0 –> (0 , y))

    To find the slope(m), use the slope formula and plug in 2 points

    m=\frac{y_2-y_1}{x_2-x_1}  

    (x₂ , y₂) should be the next point after(on the right of) (x₁ , y₁)

    If the graph shows the line crossing the y-axis, you can easily find your y-intercept. But if it’s not on the graph, you can use

    y = mx + b and plug in the slope you found, and plug in a point for (x,y) to find b
