Answer:
y = 13x + 86
Step-by-step explanation:
y−8 =13(x+6); distribute the 13
y - 8 = 13x + 78; now add 8 to both sides
y = 13x + 86; this is the slope intercept form
Answer:

Step-by-step explanation:
Given
Let x represent the number of tickets, and p the charges

A reduction of 50c gives an increment of 50 tickets.
This gives:
----

Answer: [0;+oo)
the horizontal tangent line mean y'=0
8 - 2x = 0
x = 4
