Answer:
y = -5/3x + 4
Step-by-step explanation:
slope = -5/3
-1 = -5/3(3) + b
-1 = -5 + b
4 = b
To write down a line that is perpendicular to one line, make sure that their slopes give a product of -1:
Write down an equation in the point-slope form and replace everything in and simplify:
Box A = 37.3333333333
Box B = 23.33333333333
Box C = 9.33333333333
I think it's (-3, 1)
Hope this helps! :)
