Answer:
It is not a good model because neither point lies on the line.
Step-by-step explanation:
We can test each point on the equation of the line.
7x - 10y = 3
Point: (8, 5)
7(8) - 10(5) = 56 - 50 = 6
The left side equals 6, not 3, so point (8, 5) is not on that line.
Point: (-12, -9)
7(-12) - 10(-9) = -84 + 90 = 6
The left side equals 6 again, but the right side is 3, not 6.
Answer: It is not a good model because neither point lies on the line.
Multiples of 30 : 30,60,90,120,150....
and the first one that 4 goes into evenly is 60
David's : y = 12,350 - (240x)
Amanda's : y = 12,350 + (240x)
David's equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings
