Trigonometry Examples

$x + 2 y = 2$

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

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

Step 2.3.2

Reorder terms.

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

Step 2.3.3

Remove parentheses.

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