Pre-Algebra Examples

$2 x - 5 y = 17$

Step 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 2

Rewrite in slope-intercept form.

Step 2.1

Subtract $2 x$ from both sides of the equation.

$- 5 y = 17 - 2 x$

Step 2.2

Divide each term in $- 5 y = 17 - 2 x$ by $- 5$ and simplify.

Step 2.2.1

Divide each term in $- 5 y = 17 - 2 x$ by $- 5$ .

$\frac{- 5 y}{- 5} = \frac{17}{- 5} + \frac{- 2 x}{- 5}$

Step 2.2.2

Step 2.2.2.1.1

Cancel the common factor.

$\frac{- 5 y}{- 5} = \frac{17}{- 5} + \frac{- 2 x}{- 5}$

Step 2.2.2.1.2

Divide $y$ by $1$ .

$y = \frac{17}{- 5} + \frac{- 2 x}{- 5}$

Step 2.2.3

Step 2.2.3.1.1

Move the negative in front of the fraction.

$y = - \frac{17}{5} + \frac{- 2 x}{- 5}$

Step 2.2.3.1.2

Dividing two negative values results in a positive value.

$y = - \frac{17}{5} + \frac{2 x}{5}$

Step 2.3

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

Step 2.3.1

Reorder $- \frac{17}{5}$ and $\frac{2 x}{5}$ .

$y = \frac{2 x}{5} - \frac{17}{5}$

Step 2.3.2

Reorder terms.

$y = \frac{2}{5} x - \frac{17}{5}$
