After noon, the number of people at wal-mart grows steadily until 6:00 P.M. If the equation y=228+58x represents the number of people in the store x hours afternoon:
a. how many peple were in the store at noon?
b. at what rate is the number of shoppers growing?
c. When were there 402 shoppers in the store?

a.) 228 (because x=0)
b.)rate is 58 ppl per hour (slope)
if x represents hours after noon, then at noon, x is zero hours after noon because no time has passed yet. So, for part A, you need to set x=0 and then solve.
For part b, they are essentially asking for the slope. (the rate of change of the line). If y is representing people and x is time, then as x increases by each hour, 58 more people are showing up to shop.
For part C, they want to know at what time will there be a total of 402 people shopping, so you plug that in for y and then solve.
