Formula to find the slope:
m = y2-y1 / x2-x1
(4,3); (8,5)
m= 5-3 / 8-4
m = 2/4
m = 1/2
Therefore, the slope of the line that passes through these points is 1/2
The residual plot does not show a linear model and the estimated GPA of a student who studies for 15 hours a week is 3.17
<h3>How to interpret the residual plot?</h3>
The figure (1) represents the residual plot.
In the residual plot of a linear model, the line of the plot is represented by a horizontal line
From the figure, the line of the plot is not an horizontal line.
Hence, the residual plot does not show a linear model
<h3>The estimated GPA</h3>
The number of hours is given as:
x = 15 hours
The regression line is given as:
y = 0.134x + 1.16
Substitute 15 for x
y = 0.134 * 15 + 1.16
Evaluate
y =3.17
Hence, the estimated GPA of a student who studies for 15 hours a week is 3.17

Answer:
£10,737,418.24
Step-by-step explanation:
<u>Every day amount doubles:</u>
- March 1st = 1p= 2^0 p
- March 2nd = 2*1p = 2^1 p
- March 3rd = 2*2p = 2^2 p
- ...
- March 31st = 2^30 p = 1,073,741,824 p = £10,737,418. 24
