Graph Using a Table of Values y=2.5x

$y = 2.5 x$

Step 1

Substitute $- 2$ for $x$ and find the result for $y$ .

$y = 2.5 (- 2)$

Step 2

Multiply $2.5$ by $- 2$ .

$y = - 5$

Step 3

Substitute $- 1$ for $x$ and find the result for $y$ .

$y = 2.5 (- 1)$

Step 4

Multiply $2.5$ by $- 1$ .

$y = - 2.5$

Step 5

Substitute $0$ for $x$ and find the result for $y$ .

$y = 2.5 (0)$

Step 6

Solve the equation for $y$ .

Remove parentheses.

$y = 2.5 (0)$

Multiply $2.5$ by $0$ .

$y = 0$

Step 7

Substitute $1$ for $x$ and find the result for $y$ .

$y = 2.5 (1)$

Step 8

Solve the equation for $y$ .

Remove parentheses.

$y = 2.5 (1)$

Multiply $2.5$ by $1$ .

$y = 2.5$

Step 9

Substitute $2$ for $x$ and find the result for $y$ .

$y = 2.5 (2)$

Step 10

Solve the equation for $y$ .

Remove parentheses.

$y = 2.5 (2)$

Multiply $2.5$ by $2$ .

$y = 5$

Step 11

This is a table of possible values to use when graphing the equation.

$\begin{array}{c} x & y \\ - 2 & - 5 \\ - 1 & - 2.5 \\ 0 & 0 \\ 1 & 2.5 \\ 2 & 5 \end{array}$
