Answer 1

Answer:

y=-2x+18

Step-by-step explanation:

so, we use the format y=mx+b where m and b are numbers. b=18, and m=-2, since he SPENDS 2 dollars each day. y=-2x+18 would be your answer. remember, b is also the y intercept, so one of the points that would work would be (0, 18) and the x intercept would be when y is zero, aka  0=-2x+18 which we can solve to get (9,0)
