Answer:
-1.3125
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(3.1-(-3.2))/(-2.4-2.4)
m=(3.1+3.2)/-4.8
m=6.3/-4.8
m=-1.3125

8+2x

Step-by-step explanation:
We need to understand what residual plot is?
A residual plot is a graph that shows the residuals on the vertical axis and the independent variable on the horizontal axis.
Hence, there are 2 cases related to the relation between residual plot and a linear model:
1. If the points in a residual plot are randomly dispersed around the horizontal axis => the linear model is an appropriate fit for the data
2. If the points in a residual plot has a pattern => nonlinear model is more appropriate or the line have a bad fit with the set of the data.
Hope it will find you well.
They used more cleaner in 2012 because the green line is higher in the year 2012 than it is in 2015.
4x + 7x = 33
11x = 33
x = 3
4x = 4(3) = 12
7x = 7(3) = 21
12 and 21 are how you split 33 in to a ratio of 4 to 7.
