Answer:
y= -2x+9
Step-by-step explanation:
First of all, since they need to be parallel, they must have the same slope to never intercept. Next, you can use a graphing calculator to test y-intercepts like desmos. You will find that 9 works, as it goes through (4,1) and never intercepts with the 1st line.
K = 4a + 9ab
K = a (4 + 9b)
K / (4 + 9B) = a
y=80x+16 with x representing the amount of hours rented.
Slope-intercept form is:
y=mx+b
In this case, y represents the total cost. m represents the amount per hour, x represents the amount of time, and b represents the number you add.
You would plug in the information you have (m=80 as it is $80 per hour; b=16 as it is added to the final sum):
y=80x+16
