Question

SOMEONE PLSSSS HELP!!! Explain the difference in the graphs of Car #1 and Car #2. What is the Slope of each? Why is one line steeper than the other? What does this mean in terms of the Car's Fuel Efficiency or miles per gallon?

Answer 1

Answer:

Car 1 slope = 35

Car 2 slope = 40

Red line(car 2) is steeper than the blue line(car 1)

slope is miles per gallon

Step-by-step explanation:

Slope formula is

$slope = \frac{y_2-y_1}{x_2-x_1}$

To find slope, pick two points from graph of Car 1

(4,140) (6,210)

$slope Car1= \frac{210-140}{6-4}$= 35

To find slope, pick two points from graph of Car 2

(3,120) (5,200)

$slope Car 2= \frac{200-120}{5-3}$= 40

When slope is larger then line is steeper

slope of Car 2 is greater than slope of Car1

So Red line is steeper than the blue line.

Slope is change is y over change in x

It means Change in miles over change in gallons

So slope is miles per gallon
