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

Answer

B (-4, 6)

Step-by-step explanation

Given the expression:

$y=\frac{x}{4}+5$

Substituting x = -8, we get:

$\begin{gathered} y=\frac{-8}{4}+5 \\ y=-2+5 \\ y=3 \end{gathered}$

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

Substituting x = -4, we get:

$\begin{gathered} y=\frac{-4}{4}+5 \\ y=-1+5 \\ y=4 \end{gathered}$

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