How do you model 15-25 on a number line?

To model 15 - 25 on a number line, first you draw a line and make enough lines for it to go from o to 30 on one side and 0 to -20 on the other. Then you start at the 15 mark and subtract by 25 by going to the left of 15, 25 times. Then you would get to the answer -10.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
