Answer 1

We were given that:

`\begin{gathered} y-1=-5\mleft(x-1\mright) \\ when\colon x=-4 \\ y-1=-5(-4-1) \\ y=-5(-5)+1 \\ y=25+1 \\ y=26 \\ \\ when\colon x=0 \\ y-1=-5(0-1) \\ y=-5(-1)+1 \\ y=5+1 \\ y=6 \\ \\ when\colon x=2 \\ y-1=-5(2-1) \\ y=-5(1)+1 \\ y=-5+1 \\ y=-4 \end{gathered}`

We will graph this by plotting the ordered pairs above:
