7. Which of the following statements about the line is TRUE?
B. The line has a positive slope.
C. The point (1,4) lies on the line.
D. This line is parallel to the line whose equation is y - 2x - 7.

B

Step-by-step explanation:

the line has a positive slope. you can tell by comparing the equation of the line to y=MX+c where m=slope= coefficient of x.

In this case the coefficient of x is positive 3.

a

step-by-step explanation:

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.
