Question

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

Answer 1

Answer:

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 = $\frac{x2-x1}{y2-y1}$

plug values in the formula

$\frac{74-84}{65-80}$

$\frac{-10}{-15}$

cancel - sign

$\frac{10}{15}$

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