Step-by-step explanation:
If the number of blueberries is the x value, and number of calories is the y value, then we can create the ordered pairs (5,4) (10,8) (15,12) based on the data in the table.
Plotting these on the graph is simple - just go to the x value then the y value and plot where these lines meet.
The slope of a line is always the rise over run.
Every time our x increases by 5, our y increases by 4. The rise is 4, and run is 5, so the slope is 
Hope this helped!
Answer:
6
because when you subtract 6 from 6 you get 0
6 - 6 = 0
Answer:
The speeds of the cars is: 0.625 miles/minute
Step-by-step explanation:
We use systems of equations in two variables to solve this problem.
Recall that the definition of speed (v) is the quotient of the distance traveled divided the time it took : 
. Notice as well that the speed of both cars is the same, but their times are different because they covered different distances. So if we find the distances they covered, we can easily find what their speed was.
Writing the velocity equation for car A (which reached its destination in 24 minutes) is:
Now we write a similar equation for car B which travels 5 miles further than car A and does it in 32 minutes:
Now we solve for 
in this last equation and make the substitution in the equation for car A:
So this is the speed of both cars: 0.625 miles/minute
