Write an equation to represent the
relationship “a number decreased by
11 is equal to -18.” then solve the
equation

 x-11=18

x-11=18    x=7

Step-by-step explanation:

x   -   11   =    18                       YOUR GOAL IS TO ISOLATE THE VARIABLE x.  

    -   11     -   11                        To do that you must subtract 11. Remember:                                                                                                              

18-11 = 7                              What you do to one side you must do to the other.    

x=7                                      

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
