Here is the answer from the given expression above.
The product of slopes of two perpendicular lines is equal to -1 and the slope of the line ( y = 3/4 x - 7) is 3/4.
Let the slope of the line perpendicular to it be m
m(3/4) = -1
then m=-4/3
So based on this, the correct answer would be option B. -4/3
Hope this answer helps you!
