Answer: 8.2x+7.5
Step-by-step explanation:
We have to find out the coordinates of two points to find out the slope.
according to the figure,
first point is x1 = 1 & y1 = 2
second point is x2 = 4 & y2 = 1
slope = (y2 - y1) / (x2 - x1)
= (1-2) / (4-1)
= -1 / 3
It would be a parallelogram
This can be solved using a system of equations.

Subtract y from both sides.

Substitute:

Subtract 80 from both sides:

Divide both sides by 5:

Substitute.
