Graph y-1/2x=-1

$y - \frac{1}{2} x = - 1$

Step 1

Add $\frac{x}{2}$ to both sides of the equation.

$y = - 1 + \frac{x}{2}$

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 $- 1$ and $\frac{x}{2}$ .

$y = \frac{x}{2} - 1$

Reorder terms.

$y = \frac{1}{2} x - 1$

Step 3

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

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

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

$b = - 1$

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: $(0, - 1)$

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 $- 1$ and $\frac{x}{2}$ .

$y = \frac{x}{2} - 1$

Reorder terms.

$y = \frac{1}{2} x - 1$

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

$\begin{array}{c} x & y \\ 0 & - 1 \\ 2 & 0 \end{array}$

Step 5

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

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

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

$\begin{array}{c} x & y \\ 0 & - 1 \\ 2 & 0 \end{array}$
