Question

What is the slope of the line that connects the two points (-1,5) and (2,4)

Answer 1

Answer: $-\frac{1}{3}$

Step-by-step explanation:

The equation used to find the slope of the line with two give points  and  is:

$m=\frac{Y2 - Y1}{X2 - X1}$

If the points are  and

, we only have to substitute them in the equation:

$m=\frac{4 - 5}{2 - (-1)}$

$m=\frac{-1}{2+1}$

Hence, the slope is:

$m=-\frac{1}{3}$
