What is the rate of change in the y-values with respect to the x-values?

The answer to your question is the last option

Step-by-step explanation:

Process

1.- To calculate the rate of change, calculate slope

Formula

             m = (y2 - y1) / (x2 - x1)

x1 = 1           y1 = 1200

x2 = 2         y2 = 2400

2.- Substitution

             m = (2400 - 1200) / (2 - 1)

3.- Simplification

             m = 1200 / 1

4.- Result

             m = 1200 meters / minute

The answer is 106

Step-by-step explanation:

angle B is equal to angle D

so do 91 + 15= 106

and the math at angle D is x - 15

hope this helps! :D
