Question

(6,3) and (2, -9)equation in slope intercept form

Answer 1

Let:

(x1,y1)=(6,3)

(x2,y2)=(2,-9)

$\text{slope}=m=\frac{y2-y1}{x2-x1}=\frac{-9-3}{2-6}=\frac{-12}{-4}=3$

Using the point-slope equation:

$\begin{gathered} y-y1=m(x-x1) \\ y-3=3(x-6) \\ \text{Solve for y:} \\ y=3x-15 \end{gathered}$
