Answer:
Slope = 0.65
y = 0.65x - 10.5
Step-by-step explanation:
Taking the points (-10,-17) and (-8,-15.7)
Slope = Change in y ÷ change in x
Change in y = -15.7 - -17 = 1.3
Change in x = -8 - -10 = 2
Slope = 1.3/2 = 0.65
Taking another point (x,y);
The slope intercept form is;
= 0.65
= 0.65
y + 17 = 0.65x + 6.5
y = 0.65x + 6.5 - 17
y = 0.65x - 10.5

The equation of the linear regression is
To determine the line of best fit, we make use of a graphing tool
See attachment for the graph of the line of best fit
<h3>The equation</h3>From the graphing tool, we have the following calculation summary
- Sum of X = 440
- Sum of Y = 3601.5
- Mean X = 44
- Mean Y = 360.15
- Sum of squares (SSX) = 1440
- Sum of products (SP) = 5157
The regression Equation is then represented as:
Where:
and
Also, we have:
So, the linear regression equation is:
