Question

How to solve for the Y? And how do you graph it?5x-y=-3

Answer 1

`5x-y=-3`

Solve for y:

Multiply both sides by -1:

`\begin{gathered} -1(5x-y)=-1(-3) \\ y-5x=3 \end{gathered}`

Add 5x to both sides:

`\begin{gathered} y-5x+5x=3+5x \\ y=5x+3 \end{gathered}`

Now, in order to graph the equation we need to find at least two points. In this case, let's evaluate the function for -2,-1,0,1,2:
