Write the equation of a line in point slope form that goes through the points (4,8)(-1,-12)

The point-slope form:

[tex]y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (4, 8) and (-1, -12). Substitute:

[tex]m=\dfrac{-12-8}{-1-4}=\dfrac{-20}{-5}=4\\\\\boxed{y-8=4(x-4)}[/tex]
