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
[tex]slope = \frac{y_2-y_1}{x_2-x_1}[/tex]
To find slope, pick two points from graph of Car 1
(4,140) (6,210)
[tex]slope Car1= \frac{210-140}{6-4}[/tex]= 35
To find slope, pick two points from graph of Car 2
(3,120) (5,200)
[tex]slope Car 2= \frac{200-120}{5-3}[/tex]= 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
