The table and equation below show the proportional relationship between time, in seconds, x, and distance traveled, in feet, y, for two remote-control cars. Car 1
.
y
15 75
17 85
21
105
Car 2
y = 10x
Which statement is true about the speeds of the two cars?
A
Car 1 is traveling faster than Car 2.
B
Car 2 is traveling faster than Car 1.
С
The two cars are traveling at the same speed.
D
The speeds cannot be compared because there is not enough information about Car 2.

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.
