Graph y<=2x-4 2y-x>=2

$y \leq 2 x - 4$ $2 y - x \geq 2$

Step 1

Graph $y \leq 2 x - 4$ .

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 solid line, then shade the area below the boundary line since $y$ is less than $2 x - 4$ .

$y \leq 2 x - 4$

Step 2

Graph $2 y - x \geq 2$ .

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

Solve for $y$ .

Add $x$ to both sides of the inequality.

$2 y \geq 2 + x$

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

Divide each term in $2 y \geq 2 + x$ by $2$ .

$\frac{2 y}{2} \geq \frac{2}{2} + \frac{x}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 y}{2} \geq \frac{2}{2} + \frac{x}{2}$

Divide $y$ by $1$ .

$y \geq \frac{2}{2} + \frac{x}{2}$

Simplify the right side.

Divide $2$ by $2$ .

$y \geq 1 + \frac{x}{2}$

Rearrange terms.

$y \geq \frac{x}{2} + 1$

Reorder terms.

$y \geq \frac{1}{2} x + 1$

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

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

$m = \frac{1}{2}$

$b = 1$

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

Slope: $\frac{1}{2}$

y-intercept: $(0, 1)$

Slope: $\frac{1}{2}$

y-intercept: $(0, 1)$

Graph a solid line, then shade the area above the boundary line since $y$ is greater than $\frac{1}{2} x + 1$ .

$y \geq \frac{1}{2} x + 1$

Step 3

Plot each graph on the same coordinate system.

$y \leq 2 x - 4$

$2 y - x \geq 2$

Step 4

Graph y<=2x-4 2y-x>=2
