The answer is 8. Wolfram|Alpha is great for these kinds of questions. Go to http://www.wolframalpha.com/ and math-y classes are much easier tbh
The average rate of change is calculated as the slope of the line between the two points on the graph. Since at x = 1, y = -3, and at x = 3, y = 1, these are the two points which we calculate the slope from. Using the formula
m = (y2 - y1)/(x2 - x1)
m = (1 - (-3))/(3 - 1)
m = 4/2
m = 2
Therefore the slope, or the average rate of change, between these points is 2.
Answer:
7a
Step-by-step explanation:
You would just add the two numbers and put the a in front of the answer. It would be 2 + 5 (which is 7) then put the a after the 7.
