Question

both kelly and ryan have paper planes, they make more ever day, the equations represent the number of paper planes, y, eacg person after x days.

kelly's equation y=2x+1
ryan's equation y=2x+4

do the graphs have the same slope or y-intercept?
do the graphs have different slope or y-intercept?
so can kelly and ryan start with the same or different number of planes?
can they make same or different number of planes everyday?

Answer 1

- Same slope or y-intercept?
- Same slope: both slopes = 2.
- Different y-intercepts: Kelly’s y-intercept = 1, Ryan’s = 4.

- So:
- They start with different numbers of planes (Kelly starts with 1, Ryan with 4).
- They make the same number of planes each day (both make 2 planes per day).

(Their graphs are parallel lines because the slopes are equal.)
