The graph shows the saving in Andre's bank account. What is the slope of the line?

Answers:

Slope = 5

Interpretation = Andre is saving 5 dollars per week

Work Shown:

The two points (0,40) and (4,60) are on the line

Use the slope formula

m = (y2-y1)/(x2-x1)

m = (60-40)/(4-0)

m = 20/4

m = 5

The slope is 5.

In this context, it means each time the number of weeks goes up by 1, the amount of his savings goes up by 5. In short, he's saving $5 per week.

note: the y intercept tells us that Andre started off with $40 in his account.

5

Step-by-step explanation:

slope= rise/run

=y2-y1/x2-x1

Take any two points

80-40/8-0

40/8

=5
