Find the gradient of the straight line joining A(-4, -1) to B(4, 2)

The slope of the line is  

Step-by-step explanation:

Given parameters:

                       A(-4, -1) to B(4, 2)

Unknown:

The slope of the line joining the two points

Solution:

To find the slope of the line;  we use the expression below:

  Slope  =

x₁ = -4

y₁ = -1

x₂ = 4

y₂ = 2

Input the parameters and solve;

      Slope  =

     Slope  =

The slope of the line is
