the 3rd and 4th graph? @FortyTheRapper those are the ones that's going to get X'ed out since it seems as if there decreasing so it's between the 1st and 2nd graph, yes?

Right! So now we have a graph that's a straight line and a graph that isn't. The straight line means we have a constant slope. Lets subtract the sales from week 4 and week 3, then 3 and 2, then 2 and 1 (Week 4 sales - Week 3 sales) = (75-62) = ? (Week 3 sales - Week 2 sales) = (62-50) = ? (Week 2 sales - Week 1 sales) = (50-22) = ?

(Week 4 sales - Week 3 sales) = (75-62) = 13 (Week 3 sales - Week 2 sales) = (62-50) = 12 (Week 2 sales - Week 1 sales) = (50-22) = 28 @FortyTheRapper

Right. Are 13, 12, and 28 the same number? Nope, so it's not a straight line. Giving us one answer choice

The 2nd graph??? @FortyTheRapper
FortyTheRapper
  • FortyTheRapper
The 2nd graph is a straight line, so it wouldn't be that one

Oh so it's the first graph because it kind of curves a little so it's not straight correct @FortyTheRapper it's A the first graph?
FortyTheRapper
