Question

In a graph, x represents the number of months since a

business opened, and y represents the total amount of
money the business has earned. The following three
points are from the graph:
(2, 1990) (5, 4225) (9, 7205)
Find the slope and y-intercept. Explain what each
represents.
​

Answer 1

My answer: To find the Slope the first we would need to use is the Slope-Intercept Formula. Y=mx+b. So 7205-4225=2980 and 9-5=4 So then you have to divide 2980/4=745 So the slope is 745. To find the Y-Intercept (b) we need to use the formula again. 4225= 745(5)+b so 745x5=3725 so we subtract on both sides 3725 is cancelled so 4225-3725=500 So the y-intercept is 500

Sample Response: The slope of this scenario is 745. The slope represents the profit made each month.

Explanation:

The two answers above are right.
