Answer:
The y-value will be -0.75.
Explanation:
If the rate of change is 0.25, then every time the x-value goes up by 1, 0.25 will be added to our y-value. For example, if we were to go from the x-value of 12 to 13, then our y-value would be -1.75.
If our x-value is to be 19, then we would subtract 0.25 from the y-value (0) of the x-value (20, since it is one number below.)
Therefore, 0 - 0.25 would be -0.75.
