Question

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

Answer 1

Answer/Step-by-step explanation:

An equation that describes the relationship can be written as
`y = mx`.

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

`(y_2 - y_1)/(x_2 - x_1) = (280 - 140)/(4 - 2) = (140)/(2) = 70`

Substitute m = 70 into
`y = mx`

The equation would be:

`y = 70x`

This equation can be interpreted as follows:

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