Pre-Algebra Examples

$4 x + 3 y = 5$

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 2.3.1

Reorder $\frac{5}{3}$ and $- \frac{4 x}{3}$ .

$y = - \frac{4 x}{3} + \frac{5}{3}$

Step 2.3.2

Reorder terms.

$y = - (\frac{4}{3} x) + \frac{5}{3}$

Step 2.3.3

Remove parentheses.

$y = - \frac{4}{3} x + \frac{5}{3}$
