Question

number of months cost$
1 74
2 99
3 124
4 149
The table below shows the cost for a gym membership at the local fitness center with an initial start-up fee charged in the first month. Find the slope, or monthly cost.

Answer 1

wrong

Answer 2

To find the slope, we can use the formula for finding the slope of a line given two points:

slope = (change in y) / (change in x)

Let's take the first two points on the table:

Point 1: (1, 74)
Point 2: (2, 99)

Now, calculate the change in y and change in x:

Change in y = 99 - 74 = 25
Change in x = 2 - 1 = 1

Now, calculate the slope:

slope = 25 / 1 = 25

Therefore, the monthly cost, or the slope of the line, is $25.

Answer 3

I made a mistake in my calculation. Let's correct it using the correct points from the table:

Point 1: (1, 74)
Point 2: (2, 99)

Change in y = 99 - 74 = 25
Change in x = 2 - 1 = 1

Now, calculate the slope:

slope = (change in y) / (change in x) = 25 / 1 = 25

Therefore, the monthly cost, or the slope of the line, is $25. Thank you for your patience.
