Answer 2

what would be the slope in this case?

Answer 3

I'm not sure

Answer 4

think of slope as a rate of change

Answer 5

\[\Large \text{slope} = \frac{\text{change in apples}}{\text{change in number of days}}\]

Answer 6

oh, I get it. So the slope is -3?

Answer 7

good

Answer 8

the y-intercept is the amount of apples on the first day

Answer 9

so the equation is y = -3x + 4?

Answer 10

yep notice how y = 4 when x = 0

then y = 1 when x = 1

Answer 11

okay, thank you :)

Answer 12

no problem
