Answer:

The equation that represents the graph is y = 40x

The new equation would be y = 45x

Step-by-step explanation:

As y increases by 40, x increases by 1, so 40/1, or 40

New equation: $90 per 2 months, y = 90, x = 2, 90/2 = 45

Natasha2012 [34]

Angles TRS and VRW are vertical angles, so we can set them equal to each other to get x:

x+40=3x

40=2x

20=x

So the value of x is 20
