2. What is the slope of a line that is perpendicular
to y - 4 = (x + 2)

-x?

Explanation:

1. y - 4 = (x + 2) would be y= x+6 in y=mx+b form.

2. I used a graphing calculator and found out that an equation that would be perpendicular to y= x+6 when graphed is y=-x-6.

3. The slope of y=-x-6 is -x.

4. -x

a is the right answer

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
