Question

The table represents a linear function. What is the slope of the function? x -2, -1, 0, 1, 2 ... y -2, 1, 4, 7, 10

Answer 1

The function passes through points (-2,-2) and (0,4).

The general formula for the slope of the linear function is,

`m=(y_2-y_1)/(x_2-x_1)`

Determine the slope of linear function.

`\begin{gathered} m=(4-(-2))/(0-(-2)) \\ =(6)/(2) \\ =3 \end{gathered}`

Thus slope of linear function is 3.
