Describe the key features of the functions that are needed to determine if these lines intersect.

Question

A linear function that represents the number of video games purchased at an electronics store is compared to a different linear function that represents the amount of money the store made that day

Answer 1

Well the key features that we would need to determine if they intersect would be 1. their slopes, and 2. their y-intercepts.

if two lines have the same slope, but different y-intercepts, they will never be able to intersect.

if they have the different slopes and the same y-intercept, they will intersect.

if they have different slopes and different y-intercepts, they will intersect.

sorry, I had to write this in a rush, hope this helps!
