In Exercises 13-16, estimate the slope of the line.

mrs_skeptik [129]

Answer:

Hi there!

The answer for number 13 is 2.

I picked two coordinates: (1,1) and (2,3)

Then I used the (y1-y)/(x1-x) equation to get 2.

The answer for number 14 is 2.

I picked two coordinates: (1,0) and (2,2)

Then I used the (y1-y)/(x1-x) equation to get 2.
