Yesterday, a local radio station played 89 songs prior to 10 a. m. the station also played 11 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?
a. y = 11x
b. y = x + 11
c. y = 89x + 11
d. y = 11x + 89

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
