Using the coordinates of two points (84,80) and (74,65) determine the slope of the line of best fit

2/3

Step-by-step explanation:

Given in the question two points

(84,80) and (74,65)

Here

x1 = 84

x2 = 74

y1 = 80

y2 = 65

Slope of line means gradient of line and formula to calculate gradient of line is

gradient =

plug values in the formula

cancel - sign

2/3 is the gradient of line having coordinates (84,80) and (74,65)

b) well because you get well

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis
