y = 2x
y = x + 4
y = 12 - x
Answer:
The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: . ... If coordinates of any two points of a line are given, then the rate of change is the ratio of the change in the y-coordinates to the change in the x-coordinates.

Mean is the average of all the paychecks, so it will be: (56.05 + 41.50 + 22.5 + 52.9 + 49.85 + 31)/ 6
The mean is: $42.30. So on average she earns $42.30 each week.
We can find the median by arranging from smallest to larges so: 22.5, 31, 41.5, 49.85, 52.9 and 56.05. Since we have an even number of entries, we will take the average of the middle two entries: (41.5 + 49.85)/2
So the median is: 45.68 (rounded to the nearest tenth)
Mode is the number that appears the most in a given set. In this set we can see, that no number is repeated. Therefore there is no mode.
