Question

Consider the following linear function and graph it:y = 4x − 5y = _______x, y = ______

Answer 1

y = -13

x, y = -2, 13

y = -5

x,y = 0, -5

y = 3

x, y = 2, 3

Explanation:

We have the following function:

`y=4x-5`

We will choose some values of y and then calculate x and establish the point (x, y)

`\begin{gathered} y=-13 \\ -13=4x-5 \\ 4x=-13+5 \\ x=-(8)/(4)=-2\rightarrow(-2,13) \\ \\ y=-5 \\ -5=4x-5 \\ 4x=0 \\ x=0\rightarrow(0,-5) \\ \\ y=3 \\ 3=4x-5 \\ 4x=5+3 \\ x=(8)/(4)=2\rightarrow(2,3) \end{gathered}`
