Question

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

Answer 1

2/3

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 =
`(x2-x1)/(y2-y1)`

plug values in the formula

`(74-84)/(65-80)`

`(-10)/(-15)`

cancel - sign

`(10)/(15)`

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