Answer:
B y is the total cost, x is the number of months $150 is the evaluation fee and $55 is the cost per month
Step-by-step explanation:
y = 150 +55x
This is in the form y = mx+b (y = b+mx) where m is the slope and b is the y intercept
The 150 is the initial value (y intercept) or the flat fee and 55 is the slope or the cost per month. Y is the total cost while x is the number of months
