The slope of (-4,3) (-8,5) is perpendicular to this line.
Answer: 15.
Step-by-step explanation: 15 is the only off number in the sequence, the rest are all even.
Solve for x in -7x - 8y = 9
x = -9 + 8y/7
Substitute x = -9 + 8y/7 into -4x + 9y = -22
4(9 + 8y)/7 + 9y = -22
Solve for y in 4(9 + 8y)/7 + 9y = -22
y = -2
Substitute y = -2 into x = -9 + 8y/7
x = 1
Thus,
<u>x = 1</u>
<u>y = -2</u>
