Question

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

Answer 1

Answer: m = $\frac{-7}{3}$

Step-by-step explanation:

The formula for calculating slope is given by :

m = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$x_{1}$ = -2

$x_{2}$ = 1

$y_{1}$ = 5

$y_{2}$ = -2

substituting the values :

m = $\frac{-2-5}{1-(-2)}$

m = $\frac{-7}{3}$

Answer 2

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
