MJ is placing a 6-line ad job posting for a secretary. The following piecewise function gives the price of an x-line posting. The price of the ad is $35 if the ad is 4-lines or less. The price of the ad is $35 + 8 ( x - 4 ) if the ad is more than 4 lines. How many lines is MJ placing?
Which formula should you use based on the number of lines in the ad?
Solve using the correct formula?

to be honest i don't know but i need points so

1/4 is the asnwer cuz 5/20 is the faction

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
