Graph Using a Table of Values y=7x+3

$y = 7 x + 3$

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

$y = 7 (- 2) + 3$

Simplify $7 (- 2) + 3$ .

Multiply $7$ by $- 2$ .

$y = - 14 + 3$

Add $- 14$ and $3$ .

$y = - 11$

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

$y = 7 (- 1) + 3$

Simplify $7 (- 1) + 3$ .

Multiply $7$ by $- 1$ .

$y = - 7 + 3$

Add $- 7$ and $3$ .

$y = - 4$

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

$y = 7 (0) + 3$

Solve the equation for $y$ .

Remove parentheses.

$y = 7 (0) + 3$

Simplify $7 (0) + 3$ .

Multiply $7$ by $0$ .

$y = 0 + 3$

Add $0$ and $3$ .

$y = 3$

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

$y = 7 (1) + 3$

Solve the equation for $y$ .

Remove parentheses.

$y = 7 (1) + 3$

Simplify $7 (1) + 3$ .

Multiply $7$ by $1$ .

$y = 7 + 3$

Add $7$ and $3$ .

$y = 10$

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

$y = 7 (2) + 3$

Solve the equation for $y$ .

Remove parentheses.

$y = 7 (2) + 3$

Simplify $7 (2) + 3$ .

Multiply $7$ by $2$ .

$y = 14 + 3$

Add $14$ and $3$ .

$y = 17$

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

$\begin{array}{c} x & y \\ - 2 & - 11 \\ - 1 & - 4 \\ 0 & 3 \\ 1 & 10 \\ 2 & 17 \end{array}$
