Graph 6x+4y=24

$6 x + 4 y = 24$

Step 1

Solve for $y$ .

Subtract $6 x$ from both sides of the equation.

$4 y = 24 - 6 x$

Divide each term in $4 y = 24 - 6 x$ by $4$ and simplify.

Divide each term in $4 y = 24 - 6 x$ by $4$ .

$\frac{4 y}{4} = \frac{24}{4} + \frac{- 6 x}{4}$

Simplify the left side.

Cancel the common factor of $4$ .

Cancel the common factor.

$\frac{4 y}{4} = \frac{24}{4} + \frac{- 6 x}{4}$

Divide $y$ by $1$ .

$y = \frac{24}{4} + \frac{- 6 x}{4}$

Simplify the right side.

Simplify each term.

Divide $24$ by $4$ .

$y = 6 + \frac{- 6 x}{4}$

Cancel the common factor of $- 6$ and $4$ .

Factor $2$ out of $- 6 x$ .

$y = 6 + \frac{2 (- 3 x)}{4}$

Cancel the common factors.

Factor $2$ out of $4$ .

$y = 6 + \frac{2 (- 3 x)}{2 (2)}$

Cancel the common factor.

$y = 6 + \frac{2 (- 3 x)}{2 \cdot 2}$

Rewrite the expression.

$y = 6 + \frac{- 3 x}{2}$

Move the negative in front of the fraction.

$y = 6 - \frac{3 x}{2}$

Step 2

Rewrite in slope-intercept form.

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Reorder $6$ and $- \frac{3 x}{2}$ .

$y = - \frac{3 x}{2} + 6$

Write in $y = m x + b$ form.

Reorder terms.

$y = - (\frac{3}{2} x) + 6$

Remove parentheses.

$y = - \frac{3}{2} x + 6$

Step 3

Use the slope-intercept form to find the slope and y-intercept.

Find the values of $m$ and $b$ using the form $y = m x + b$ .

$m = - \frac{3}{2}$

$b = 6$

The slope of the line is the value of $m$ , and the y-intercept is the value of $b$ .

Slope: $- \frac{3}{2}$

y-intercept: $(0, 6)$

Slope: $- \frac{3}{2}$

y-intercept: $(0, 6)$

Step 4

Any line can be graphed using two points. Select two $x$ values, and plug them into the equation to find the corresponding $y$ values.

Write in $y = m x + b$ form.

Reorder $6$ and $- \frac{3 x}{2}$ .

$y = - \frac{3 x}{2} + 6$

Reorder terms.

$y = - (\frac{3}{2} x) + 6$

Remove parentheses.

$y = - \frac{3}{2} x + 6$

Create a table of the $x$ and $y$ values.

$\begin{array}{c} x & y \\ 0 & 6 \\ 2 & 3 \end{array}$

Step 5

Graph the line using the slope and the y-intercept, or the points.

Slope: $- \frac{3}{2}$

y-intercept: $(0, 6)$

$\begin{array}{c} x & y \\ 0 & 6 \\ 2 & 3 \end{array}$
