The slope is 2.
Reason: you find the slope by dividing the difference of the y-coordinates (5 and 9) by the difference of the x coordinates (1 and 3)
9-5=4
3-1=2
4 divided by 2 =2
4x(-2) + 4 x 7 4x5 + 2x(-1) =[-8 20]
[28 -2 ]
The mean of this data is: 11
The median of this data is: 11
The mean and median of this data is the same in this case.
Hope this helps
Have a great day :)
Here is a model I have made (I'm not a great artist). There are 42 circles in total, placed in 7 columns. Each column has 6 circles. This model represents 42/7 by splitting 42 into 7 parts, which are the columns, and showing that each column has 6 circles, which is the answer to 42/7.
