The table below shows the number of jumping jacks completed after a given period of time in minutes.
Time (minutes) Jumping Jacks
1 50
2 100
3 150
4 200
Considering the jumping jacks: 50, 100, 150, 200, what is the common difference?
The common difference in this scenario is 50.
Now, think of this table as a set of ordered pairs. This means that the first row can be placed in an ordered pair as (1, 50). The second row can be written as (2, 100). Using this, what is the slope of the line that connects the first two points?
To find the slope of the line that connects the first two points, we can use the formula for slope:
slope = (change in y)/(change in x)
In this case, the first two points are (1, 50) and (2, 100).
The change in y is 100 - 50 = 50.
The change in x is 2 - 1 = 1.
So, the slope = (50)/(1) = 50.
What is the slope of the line that connects the 3rd and 4th point?
To find the slope of the line that connects the third and fourth points, we can use the formula for slope:
slope = (change in y) / (change in x)
In this case, the third point is (3, 150) and the fourth point is (4, 200).
The change in y is 200 - 150 = 50.
The change in x is 4 - 3 = 1.
So, the slope = (50) / (1) = 50.
What is the slope of the line that connects the 1st and the 4th point?
To find the slope of the line that connects the first and fourth points, we can use the formula for slope:
slope = (change in y) / (change in x)
In this case, the first point is (1, 50) and the fourth point is (4, 200).
The change in y is 200 - 50 = 150.
The change in x is 4 - 1 = 3.
So, the slope = (150) / (3) = 50.
