What is the slope of the line (2,3) (1,-2)?

Slope = 5

Step-by-step explanation:

Points to remember

slope of the line  passing through the point (x₁, y₁) and (x₂, y₂) is given by

Slope m = (y₂ - y₁)/(x₂ - x₁)

To find the slope of the given line

Here (x₁, y₁) = (2, 3)  and (x₂, y₂) = (1, -2)

Slope m = (y₂ - y₁)/(x₂ - x₁)

 = (-2 - 3)/(1 - 2)

 = (-5)/(-1)

 = 5

Therefore the slope of given line is 5
