The graph for a yellow car traveling 40 mph is added. the blue car travels 50 mph, and the red car is traveling 60 mph. order the slopes of the lines representing the cars' speeds from least to greatest. a) red car, blue car, yellow car b) blue car, yellow car, red car c) red car, yellow car, blue car d) yellow car, blue car, red car

D) yellow car, blue car, red car

Step-by-step explanation:

Since, the linear equation that shows the motion of an object moving with the constant speed is,

y = mx

Where,

slope of the line, m = speed of the object

Thus, slope ∝ speed,

i.e. the slope of the line representing motion of a car with the higher speed will be higher,

Here, Speed of,

yellow car = 40 mph,

blue car = 50 mph,

red car = 60 mph,

∵ 60 > 50 > 40

Hence, the order of the slopes of the lines representing the cars from the least to greatest would be,

yellow car, blue car, red car

OPTION D is correct.
