<PRE><B>Question 1034305</B>
Yesterday, a local radio station played 90 songs prior to 10 a.m. The station also played 10 songs per hour for the remainder of the day. 
If a person listened to the radio station yesterday afternoon for x hours, which of the following equations can be used to find the number of songs the person listened to? 
----
If x is zero, the number of songs is 90 ; that is the y-intercept
When x increases by 1, # of songs increases by 10 ; that is the slope
-----
Equation:
S(x) = 10x + 90
