Which describes the slope of this line? a. positive slope b. negative slope c. zero slope d. undefined slope

B. negative slope

Step-by-step explanation:

There are 4 types of slope:

Horizontal line: slope is 0

Vertical line: there is no slope

Diagonal line goes up to the right: positive slope

Diagonal line goes down to the right: negative slope

In this case, you have a diagonal line that goes down to the right, so the slope is negative.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
