Question

Identify the slope of the line that passes through the points (-2,5) and (1,-2)

Answer 1

m = -7/3 Or -2.333


The slope formula

slope = (y₂ - y₁) / (x₂ - x₁)

Notice that the slope of a line is easily calculated by hand using small, whole number coordinates. The formula becomes increasingly useful as the coordinates take on larger values or decimal values

Answer 2

Answer: m =
`(-7)/(3)`

Explanation:

The formula for calculating slope is given by :

m =
`(y_(2)-y_(1))/(x_(2)-x_(1))`

`x_(1)` = -2

`x_(2)` = 1

`y_(1)` = 5

`y_(2)` = -2

substituting the values :

m =
`(-2-5)/(1-(-2))`

m =
`(-7)/(3)`
