The equation for line q can be written as y = x + 9. Liner includes the point (10, -7) and is perpendicular to line q. What is the equation of line r?
Write the equation in slope-intercept form. Write the numbers in the equation as proper
fractions, improper fractions, or integers.

y = -x + 3.

Step-by-step explanation:

The slope of line q is 1.

The slope if the line r = -1/m = -1/1 = -1.

So we can write r as y = -x + b.

When x = 10 y = -7 on line r so

-7 = -10 + b

b = -7 + 10

b = 3

Line  r is y = -x + 3.
