Answer:
y = 2x + 8
Step-by-step explanation:
Find the slope of a line between (-8,-8) and (-9,-10) using m = 
, which is the change in y over the change in x.
Substitute in the values of x and y into the equation to find slope.
Simplify.
Simplify the numerator.
Multiply -1 by -8
Add -10 and 8
Simplify the denominator.
Multiply -1 by -8
Add -9 and 8.
Divide -2 by -1.
Using the point slope form 
plug in m = 2, 
Solve for y.

Answer:
$0.03
Step-by-step explanation:
chips: 7.84/16=0.49
pretzels: 12.48/24=0.52
0.52=0.49=0.03
Answer:
0.04
Step-by-step explanation:
1. 9/10 = 0.9 and 13/15 = 0.86
2. Subtract 0.9 and 0.86
3. You should end up with 0.04
Remember when a number goes like 0.86666666666 to use 0.86 or if it has 0.86666666667 to use 0.87 because you would be simplifying it.
Based on the fact that the radius of the snowball increases by 0.36 inches every second, the linear function can be found to be y = 0.36x + 1.66
<h3>How to find the linear function?</h3>
The linear function is the function that shows how to change in the rate of the independent variable would affect the rate of change in the dependent variable.
The linear function takes the form:
y = mx + b
y = dependent variable
m = slope or change in radius of snowball
x = seconds
b = y-intercept
Solving for the y-intercept gives:
3.1 = 0.36(4) + b
b = 3.1 - 1.44
= 1.66
The linear function is therefore:
y = 0.36x + 1.66
