Use two sets of coordinates to write an equation
to describe the relationship.

Answer/Step-by-step explanation:

An equation that describes the relationship can be written as .

Using the two sets of coordinates, (2, 140) and (4, 280), calculate the slope (m) as shown below:

Substitute m = 70 into

The equation would be:

This equation can be interpreted as follows:

The heart's resting rate is 70 beats each minute.

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
