Answer:

x = 7. Answer Choice A

Step-by-step explanation:

We first use the point slope formula to find an equation for this line.

[tex]y-14=\frac{21}{2} (x-9)[/tex]. We can simplify this to [tex]y=\frac{21}{2}x-\frac{161}{2}[/tex].

We can substitute in -7 for the y value and continue to solve for x.

[tex]-7=\frac{21}{2}x-\frac{161}{2}[/tex]

Solving this equation, we find that x = 7.
