iren [92.7K]

Answer:

$x=-9$

Step-by-step explanation:

Perpendicular lines means that their slopes are negative reciprocals of each other.

In other words, when you multiply the 2 slopes, that will gives us -1.

Slope's formula is m = $\frac{y_2-y_1}{x_2-x_1}$

Taking the first two points, we have:

$\frac{y_2-y_1}{x_2-x_1}\\=\frac{2--6}{7-11}\\=\frac{8}{-4}\\=-2$

Taking the second two points, we have:

$\frac{-2-4}{x-3}\\=\frac{-6}{x-3}$

Now multiplying these 2 expressions and equating it to -1, we can solve for x:

$-2*\frac{-6}{x-3}=-1\\\frac{12}{x-3}=-1\\12=-1(x-3)\\12=-x+3\\x=3-12\\x=-9$

x = -9
