Answer:
3
Step-by-step explanation:
The average rate of change is the slope of the line between the points at the ends of the interval: (1, -2) and (3, 4). That is given by the slope formula ...
m = (y2 -y1)/(x2 -x1)
m = (4 -(-2))/(3 -1) = 6/2
m = 3
The average rate of change on the interval is 3.

Step-by-step explanation:
Ashley bought two packets less so the $5 is the cost of two packets so just divide 5 by 2
3x-5y=20 the answer is y= 4x+-1/3
Answer: 195 = 35x + 20
Step-by-step explanation: This follows the y = mx + b formula.
y is your total, what the equation equals, and in this case it is your total cost of $195.
x is your independent variable, and time is always independent. When m is $35, you can plug in any hour (time!) for the x.
b is your initial value. This is what you start with, and in this case, it is your $20 equipment fee. You KNOW you have to pay that.
Hope this helps!
