Graph y<2x+4 -3x-2y>=6

$y < 2 x + 4$ $- 3 x - 2 y \geq 6$

Step 1

Graph $y < 2 x + 4$ .

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

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

$y = m x + b$

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

$m = 2$

$b = 4$

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

Slope: $2$

y-intercept: $(0, 4)$

Slope: $2$

y-intercept: $(0, 4)$

Graph a dashed line, then shade the area below the boundary line since $y$ is less than $2 x + 4$ .

$y < 2 x + 4$

Step 2

Graph $- 3 x - 2 y \geq 6$ .

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

Solve for $y$ .

Add $3 x$ to both sides of the inequality.

$- 2 y \geq 6 + 3 x$

Divide each term in $- 2 y \geq 6 + 3 x$ by $- 2$ and simplify.

Divide each term in $- 2 y \geq 6 + 3 x$ by $- 2$ . When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.

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

Simplify the left side.

Cancel the common factor of $- 2$ .

Cancel the common factor.

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

Divide $y$ by $1$ .

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

Simplify the right side.

Simplify each term.

Divide $6$ by $- 2$ .

$y \leq - 3 + \frac{3 x}{- 2}$

Move the negative in front of the fraction.

$y \leq - 3 - \frac{3 x}{2}$

Rearrange terms.

$y \leq - \frac{3 x}{2} - 3$

Reorder terms.

$y \leq - (\frac{3}{2} x) - 3$

Remove parentheses.

$y \leq - \frac{3}{2} x - 3$

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

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

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

$b = - 3$

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: $(0, - 3)$

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

y-intercept: $(0, - 3)$

Graph a solid line, then shade the area below the boundary line since $y$ is less than $- \frac{3}{2} x - 3$ .

$y \leq - \frac{3}{2} x - 3$

Step 3

Plot each graph on the same coordinate system.

$y < 2 x + 4$

$- 3 x - 2 y \geq 6$

Step 4

Graph y<2x+4 -3x-2y>=6
