Dominic spends a winter day recording the temperature once every three hours for science class. At 9 am, the temperature was -2.6°F. Between 9am and noon, the temperature rose 3.2°F. Between noon and 3pm, the temperature decreased by 12.4°F. Between 3pm and 6pm, the temperature dropped 5.1°F. What was the temperature at 6pm?

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.
