*
1 point
An equation that would represent Plan 2 would be ____.
*
1 point
y = x + 4
y = 4x + 4
4x + 0y = 4
y = 4x
Check the box for the 2 statements that are true.
*
2 points

Answer 1

Plan 1: y = 2.5x + 7

Plan 2: y = 4x

True statements (check these two):
- Plan 1 is better when you watch more than 5 videos
- Plan 2 is proportional

(Reason: break-even when 2.5x + 7 = 4x ⇒ x = 7/1.5 = 14/3 ≈ 4.67, so for x > 14/3 (and thus for more than 5 videos) Plan 1 is cheaper. Plan 2 is proportional because y = 4x passes through the origin.)
