Question

Which ordered pair does not lie on the graph of Y=x/4+5?A (-8,3)B (-4,6)C (12,8)D (20,10)

Answer 1

B (-4, 6)

Explanation

Given the expression:

`y=(x)/(4)+5`

Substituting x = -8, we get:

`\begin{gathered} y=(-8)/(4)+5 \\ y=-2+5 \\ y=3 \end{gathered}`

Then, the point (-8, 3) lies on the line.

Substituting x = -4, we get:

`\begin{gathered} y=(-4)/(4)+5 \\ y=-1+5 \\ y=4 \end{gathered}`

Then, the point (-4, 6) does not lie on the line, the point (-4, 4) does.
