Slope is rise over run or (y₁-y₂)/(x₁-x₂)
(x,y)
(1,3)
(3,-2)
(3-(-2))/(1-3)=(3+2)/(1-3)=5/-2
slope is -5/2
Answer:
Solution-
We know that,
Residual value = Given value - Predicted value
The table for residual values is shown below,
Plotting a graph, by taking the residual values on ordinate and values of given x on abscissa, a random pattern is obtained where the points are evenly distributed about x-axis.
We know that,
If the points in a residual plot are randomly dispersed around the horizontal or x-axis, a linear regression model is appropriate for the data. Otherwise, a non-linear model is more appropriate.
As, in this case the points are distributed randomly around x-axis, so the residual plot show that the line of regression is best fit for the data set.
Hope this helps!

Answer:
5x² - 31x + 30
Step-by-step explanation:
(5 - x)(6 - 5x)
= 30 - 25x - 6x + 5x²
= 30 - 31x + 5x²
= 5x² - 31x + 30
