The explanation about the graph is illustrated below.
<h3>How to illustrate the graph?</h3>
The graph shows 0 to 30 on the x-axis at increments of 5 and 0 to 12 on the y-axis at increments of 1. The label on the x-axis is Temperature in degrees C, and the label on the y axis is the Number of Sweaters Sold.
If you will draw lines through, (12.5,6) and (15,4), it will best represent a line of best fit, because most of the points on the same and opposite sides of line are equidistant from each other.
Equation of line passing through (12.5,6) and (15,4) A line of best is the line that passes through all or some points or only through a single point, which describes the relationship between x and y values of data set
4x + 5y = 80
5y = -4x + 80.
y = -4x/5 + 16
Slope = -4/5 and y intercept is 16.

Answer:
Step-by-step explanation:
E(-1,6) & F(-2,-10)

Slope of the line perpendicular to this line = -1/m = -1/16
Answer:
D
Step-by-step explanation:
11x + 14 < -8
Cancel the addition by subtracting
11x + 14 - 14 < -8 - 14
11x < -22
11x / 11 < -22/11
x < -2
Therefore, the answer is D
