Answer:
y=-3/2x+4
Step-by-step explanation:
In order to solve this you need to graph the points and then draw a line threw them. The place where the line crosses through the y-intercept is the value for b in y=mx+b.
$30 is your constant
Months would be your independent variable
Total cost would be dependent
Therefore, your total cost would “depend” on the number of months “independent” times your constant of 30
Answer:
The first answer, 3 times the square root of x squared is correct.

The final simplified answer is 6a + 5.
