Question

Matt is training for a road race. The graph shows the distance he covers when running. Which ordered pair shows that Matt ran 20 miles in 4 hours?

A. (20, 20)
B. (4, 4)
C. (20, 4)
D. (4, 20)

Answer 1

(4,20)

Explanation:

The question is asking which of the following ordered pairs will equal 20:4

We can cross out options A & B they are not what we are looking for.

The “ X-Coordinate “ equals the hours.

The “ Y-Coordinate “ equals the miles

X-Coordinate always comes first before the Y-Coordinate.

Our hours is 4

Our miles is 20

Since X-Coordinate goes first:

( 4 , ? )

The unknown will equal 20, since miles is represented as “ Y-Coordinate”

( 4 , 20 )

Therefore, the answer to your problem is, D, (4,20)
