The equation of line p is y= –9/8x − 6 Line
q ,
which is perpendicular to line
p ,
includes the point
(7, 7) . What
is the equation of line
q ?

the equasion of q is y=8/9x + 7/9

Step-by-step explanation:

1. to find the slope perpendicular to the slope of the first equasion, you have to find the negative recipocal, an easy way to find that is to switch the numerator and denominator of the slope as well as multiplying it by -1

2. now that you have found the slope that is perpendicular, your second equasion so far is y= 8/9x, to find the y-intercept, you plug in (7, 7) to x and y, making the equasion 7=8/9(7) + x, in this equasion x is the y intercept

3. when you solve for x for finding the y-intercept, x=7/9, which makes the equasion y=8/9x + 7/9
