Distance traveled d equals the product of the rate r and the time t. Given the rate and time traveled, find the distance traveled:

Rate = 15 miles per hour 2. Rate = 36 miles per hour

Time = 3 hours time = 1.5 hours

Which of the following is the graph of ? increased from 1160 to 2000. What was the average change in the number of books in the library for each of the seven years?

Which of the following is the graph of ? increased from 1160 to 2000. What was the average change in the number of books in the library for each of the seven years?

Do the following percent problems: increased from 1160 to 2000. What was the average change in the number of books in the library for each of the seven years?

1. What is 70% of 135 2. What percent is 48 of 96

What is the slope of increased from 1160 to 2000. What was the average change in the number of books in the library for each of the seven years? each graph:

m = -2/3

m = 1

What is the increased from 1160 to 2000. What was the average change in the number of books in the library for each of the seven years?y-intercept of the graph ofeachequation:

1. 3x – 6y = 12 2. x + 5y = -25

To find the y-intercept, you plug in ZERO FOR X

3(0) – 6y = 12

-6y = 12

-6 -6

y = -2

(0,-2)

(0) + 5y = -25

5y = -25
