Question

Find the equation of a line in the form y=Mx+b MATH HW

Answer 1

Using y=mx+b form first we calculate the slope.

We'll use points (0,-8) and (-8,0).

`\begin{gathered} m=(-8-0)/(0--8) \\ m=-(8)/(8) \\ m=-1 \end{gathered}`

Next we calculate our b intercept

`\begin{gathered} 0=-1(-8)+b \\ b=-8 \end{gathered}`

So the equation is y=-x-8
