Question

The equation y = 1.6x represents the number of laps Henry can swim over time, where y is the number of laps and x is time in minutes. The table shows the number of laps Larry can swim over time.

How many laps can each boy complete per minute, and who can swim laps at a faster rate?

Henry: laps per minute

Larry: laps per minute

The boy who swims at a faster rate is . (Type H for Henry or L for Larry)


Larry
Time (min) 2.5 4 5.5 8
Laps completed 4.5 7.2 9.9 14.4

Answer 1

ok so do you know the formula to find the slope?

Answer 2

no..

Answer 3

\(\Large \dfrac{y_2 - y_1}{x_2-x_1}\)

Answer 4

\(\dfrac{7.2 - 4.5}{4 - 2.5}\)
i want you to subtract 7.2 - 4.5 and 4 - 2.5 and the divide what you get

Answer 5

OKay thanks :)

Answer 6

ok so what do you get?

Answer 7

1.35?

Answer 8

no it's 1.8
