Answer:
a·2
Step-by-step explanation:
The rate is 0.30 km/min. The rate in linear functions, which must be assumed with only two given points can be traced to calculating the slope (m) of the line or rate.
m= (y2-y1) / (x2-x1)
with our two given points (x,y) we fill out the equation as:
M= (12 - 0) / (40 - 0) or M = 12/40 = 0.3
keeping our units intact 12 km / 40 min so the answer is 0.3 km/min
She’ll need 8 treat bags, and she’ll have 1 lollipop left over.
Answer:

Step-by-step explanation:
Represent the SAT score with y and the rate with r.
So, we have:


Required
Determine the equation in slope intercept form
First, we calculate the slope

This gives:


Convert percentage to decimal


Multiply by 1000/1000



The equation is then calculated as:

This gives:

Convert percentage to decimal



Make y the subject


Infinitely many, because x can be anything and the equation will still be valid
