Graph y>=2x+1 y<=2x-2

$y \geq 2 x + 1$ $y \leq 2 x - 2$

Step 1

Graph $y \geq 2 x + 1$ .

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 $y = m x + b$ .

$m = 2$

$b = 1$

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

Slope: $2$

y-intercept: $(0, 1)$

Slope: $2$

y-intercept: $(0, 1)$

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

$y \geq 2 x + 1$

Step 2

Graph $y \leq 2 x - 2$ .

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 $y = m x + b$ .

$m = 2$

$b = - 2$

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

Slope: $2$

y-intercept: $(0, - 2)$

Slope: $2$

y-intercept: $(0, - 2)$

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

$y \leq 2 x - 2$

Step 3

Plot each graph on the same coordinate system.

$y \geq 2 x + 1$

$y \leq 2 x - 2$
