-3x+y=10 is the answer. If you plug the coordinates in to the respective spots (-2 for x and 4 for y), you will get an equal true statement.
You got add all the numbers up and divide it by how many numbers there are to get the average.
9.4 +9.7 + 9.9 + 9.8 = 38.8 divided by 4 =9.7 is Joey's average.
9.5 +9.2 +9.7 +9.6 =38 divided by 4 = 9.5 is Carlos' average.
Joey has more average by 0.2.
To find the gradient you do change in y/change in x so...
-12 - 0
————- = -12/4 = -3
0 - - 4
Hope this helps! Any questions let me know :)
There are 60 buses, each has 34 students
So we would multiply to find our answer. 34*60=2040
The x-intercepts are: -0.5 and 2.
