Well, first off, let's find what is the slope of BC

now, a line perpendicular to that one, will have a negative reciprocal slope, thus

now, we know the slope "m" of AB is -2 then, thus
The slope is 2-2/6-6 which is zero . So the slope is no slope
Answer:
Step-by-step explanation:--0.9
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:
---- 

Required
Determine the demand function
First, calculate the slope:




So, the equation is:




Hence, the function is:
