Answer:

The slope of the line that contains the points (-1, 2) and (4, 3) is:

  • Slope = m =  1 / 5        

Step-by-step explanation:

Given the points

  • (-1, 2)
  • (4, 3)

Finding the slope between (-1, 2) and (4, 3)

\left(x_1,\:y_1\right)=\left(-1,\:2\right),\:\left(x_2,\:y_2\right)=\left(4,\:3\right)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [3 - 2] / [4 - (-1)]

               = 1 / 5                  

Thus, the slope of the line that contains the points (-1, 2) and (4, 3) is:

  • Slope = m =  1 / 5
