Answer:
y= 2x +7
Step-by-step explanation:
<u>Slope-intercept</u><u> </u><u>form</u><u>:</u>
y= mx +c, where m is the slope and c is the y-intercept.
Given that the slope is 2, m=2.
y= 2x +c
Given that the y-intercept is -7, c = -7.
y= 2x +7
She will use 13 1/4 cups of oatmeal
Reasonable to estimate that 120/6 = 20 (because 20*6=120)...so you know it's going to be close and therefore "reasonable"


Plug slope in the general equation : y = mx + b
y = -x + b
5 = -4 + b
b = 9
Plug y-intercept int the general equation:
y = -x + 9
Answer: y = -x + 9
The exponential growth is:
1,4, and 5
Since they are increasing exponentially
