Find the slope of a line that passes through (-2,1) and (4,9)

m = 4/3

Step-by-step explanation:

To find the slope of a line use the formula, where "m" means slope:

*You don't need to show this part on paper*

Choose which point you want to be point 1 and point 2. Remember the points are written (x, y).

Point 1: (-2, 1)       x₁ = -2  y₁ = 1

Point 2: (4, 9)      x₂ = 4   y₂ = 9

Substitute the coordinates into the formula:

*Show this part on paper*

        Simplify

               Reduce by dividing by 2

              Slope

The slope of the line is 4/3

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
