The slope of the line of best fit, where y is the total number of ice cream sales and x is the average daily temperature, is 1.4.
A line's slope is how steeply it slopes from LEFT to RIGHT. The slope of a line is determined by dividing its rise, or vertical change, by its run, or horizontal change. No matter which two locations on the line you choose, the slope of a line is always constant .
calculation
The following is the breakdown of the points for this issue:
(56.1, 107), (60.3, 116), (64.2, 120), (66.4, 122), (71.3, 125), (73.9, 130), (74.2, 132), (75.2, 135), (80.2, 141), (84.8, 151). (84.8, 151).
The equation appears as follows when these points are entered into a calculator:
y = 1.4x + 26.8.
The function's slope is therefore:
m = 1.4
The slope of the line of best fit, where y is the total number of ice cream sales and x is the average daily temperature, is 1.4.
