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.
Answer:
B, A, E, D
Step-by-step explanation:
Hope this helps and can I have brainliest!
I know, you have to divide 90 by what ever the length is, then you have to figure out where the points are. So it should be.... D!!!
Answer:
y= -1/3x+9.2
Step-by-step explanation:
I believe that it is 9.2 although it could be another number in the 9's.
The slope is (rise) -1 and (run) 3 and the line crosses the y-intercept at what it looks like 9.2
I think maybe A Im not 100% sure tho
