Answer:
Line A: y=1.25x+10
Line B: y=0.75x+5
Explanation:
Line A: 1.25(20)+10
25+10=35
When x is 20, y is 35. Which is a point on line A so the equation fits the line.
Line B: 0.75(20)+5
15+5=20
When x is 20, y is 20. This equation fits the line of the graph since the y values are the same when x is 20.
Hope this helps! :)
