Question

I need help with my math

Answer 1

Let:

`\begin{gathered} (x1,y1)=(3,30) \\ (x2,y2)=(5,50) \\ so\colon \\ m=(y2-y1)/(x2-x1)=(50-30)/(5-3)=(20)/(2)=10 \\ \end{gathered}`

using the point-slope equation:

`\begin{gathered} y-y1=m(x-x1) \\ y-30=10(x-3) \\ y-30=10x-30 \\ y=10x \end{gathered}`

so:

`\begin{gathered} (6,60) \\ 60=10(6) \\ 60=60 \\ True \end{gathered}`

Answer:

C (6,60)
