$y = \frac{5}{6} x - 6$

Step 1

Rewrite in slope-intercept form.

Step 1.1

The slope-intercept form is

$y = m x + b$ , where

$m$ is the slope and

$b$ is the y-intercept.

$y = m x + b$

Step 1.2

Reorder terms.

$y = \frac{5}{6} x - 6$

Step 2

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

Step 2.1

Find the values of

$m$ and

$b$ using the form

$y = m x + b$ .

$m = \frac{5}{6}$

$b = - 6$

Step 2.2

The slope of the line is the value of

$m$ , and the y-intercept is the value of

$b$ .

Slope:

$\frac{5}{6}$

y-intercept:

$(0, - 6)$

Slope:

$\frac{5}{6}$

y-intercept:

$(0, - 6)$

Step 3

Any line can be graphed using two points. Select two

$x$ values, and plug them into the equation to find the corresponding

$y$ values.

Step 3.1

Reorder terms.

$y = \frac{5}{6} x - 6$

Step 3.2

Create a table of the

$x$ and

$y$ values.

$\begin{array}{c} x & y \\ 0 & - 6 \\ 6 & - 1 \end{array}$

Step 4

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

Slope:

$\frac{5}{6}$

y-intercept:

$(0, - 6)$

$\begin{array}{c} x & y \\ 0 & - 6 \\ 6 & - 1 \end{array}$

Step 5

$y = \frac{5}{6} x - 6$
