Question

Part A Which graph has the following solution set (-9,10) (-6,5) (0,-5) (3,-10)Part B Write the equation of the graph from part a.

Answer 1

`\begin{gathered} \text{Let:} \\ (x1,y1)=(-9,10) \\ (x2,y2)=(-6,5) \\ m=(y2-y1)/(x2-x1)=(5-10)/(-6-(-9))=(-5)/(3)=-(5)/(3) \\ \end{gathered}`

Using the point-slope equation:

`\begin{gathered} y-y1=m(x-x1) \\ y-10=-(5)/(3)(x+9) \\ y-10=-(5)/(3)x-15 \\ y=-(5)/(3)x-5 \end{gathered}`
