Answer:
28
Step-by-step explanation:
First, you start with 11-4, which equals 7.
Then, you multiply 7x8 which equals 56.

I believe it is C. a histogram
(if it’s not then sorry)
(4,5)(2,1)
slope = (1 - 5) / (2 - 4) = -4/-2 = 2
(-2,3)(-4,4)
slope = (4 - 3) / (-4 - (-2) = 1/(-4 + 2) = -1/2
2 and -1/2 are negative reciprocals of each other....therefore, ur lines are perpendicular <==
