## anonymous one year ago PLEASE HELP!! How do you turn this into an equation in slope-intercept form? Kelly had 4 apples in her kitchen on Monday. On Tuesday, only 1 was left.

@Hero @jim_thompson5910

2. jim_thompson5910

what would be the slope in this case?

3. anonymous

I'm not sure

4. jim_thompson5910

think of slope as a rate of change

5. jim_thompson5910

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

6. anonymous

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

7. jim_thompson5910

good

8. jim_thompson5910

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

9. anonymous

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

10. jim_thompson5910

yep notice how y = 4 when x = 0 then y = 1 when x = 1

okay, thank you :)

no problem
