Graph y>x-1 y>-2x

$y > x - 1$ $y > - 2 x$

Step 1

Graph $y > x - 1$ .

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 $y = m x + b$ .

$m = 1$

$b = - 1$

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

Slope: $1$

y-intercept: $(0, - 1)$

Slope: $1$

y-intercept: $(0, - 1)$

Graph a dashed line, then shade the area above the boundary line since $y$ is greater than $x - 1$ .

$y > x - 1$

Step 2

Graph $y > - 2 x$ .

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 $y = m x + b$ .

$m = - 2$

$b = 0$

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

Slope: $- 2$

y-intercept: $(0, 0)$

Slope: $- 2$

y-intercept: $(0, 0)$

Graph a dashed line, then shade the area above the boundary line since $y$ is greater than $- 2 x$ .

$y > - 2 x$

Step 3

Plot each graph on the same coordinate system.

$y > x - 1$

$y > - 2 x$
