Answer: what’s the question
?
Step-by-step explanation:
7x - 5y = -140
Solve for y.
7x + 140 = 5y
5y = 7x + 140
y = (7/5)x + 28
To plot the line, draw a point at (0, 28).
Then go up 7 units and right 5 units and draw a point there.
Connect the two points with a segment and extend it in both directions.
