Question

determine the equation of the line.(type an equation. simplify ur answer. type your answer in slope-intercept form)

Answer 1

Let:

`\begin{gathered} (x1,y1)=(0,-8) \\ (x2,y2)=(4,8) \end{gathered}`

The slope m is given by:

`\begin{gathered} m=(y2-y1)/(x2-x1) \\ m=(8-(-8))/(4-0) \\ m=(16)/(4) \\ m=4 \end{gathered}`

Using the point-slope equation:

`\begin{gathered} y-y1=m(x-x1) \\ y-(-8)=4(x-0) \\ y+8=4x \\ y=4x-8 \end{gathered}`
