Find Any Equation Perpendicular to the Line 2x-y=16

$2 x - y = 16$

Step 1

Choose a point that the perpendicular line will pass through.

$(0, 0)$

Step 2

Solve $2 x - y = 16$ .

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

$- y = 16 - 2 x$

Divide each term in $- y = 16 - 2 x$ by $- 1$ and simplify.

Divide each term in $- y = 16 - 2 x$ by $- 1$ .

$\frac{- y}{- 1} = \frac{16}{- 1} + \frac{- 2 x}{- 1}$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{y}{1} = \frac{16}{- 1} + \frac{- 2 x}{- 1}$

Divide $y$ by $1$ .

$y = \frac{16}{- 1} + \frac{- 2 x}{- 1}$

Simplify the right side.

Simplify each term.

Divide $16$ by $- 1$ .

$y = - 16 + \frac{- 2 x}{- 1}$

Move the negative one from the denominator of $\frac{- 2 x}{- 1}$ .

$y = - 16 - 1 \cdot (- 2 x)$

Rewrite $- 1 \cdot (- 2 x)$ as $- (- 2 x)$ .

$y = - 16 - (- 2 x)$

Multiply $- 2$ by $- 1$ .

$y = - 16 + 2 x$

Step 3

Find the slope when $y = - 16 + 2 x$ .

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 $- 16$ and $2 x$ .

$y = 2 x - 16$

Using the slope-intercept form, the slope is $2$ .

$m = 2$

Step 4

The equation of a perpendicular line must have a slope that is the negative reciprocal of the original slope.

$m_{perpendicular} = - \frac{1}{2}$

Step 5

Find the equation of the perpendicular line using the point-slope formula.

Use the slope $- \frac{1}{2}$ and a given point $(0, 0)$ to substitute for $x_{1}$ and $y_{1}$ in the point-slope form $y - y_{1} = m (x - x_{1})$ , which is derived from the slope equation $m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ .

$y - (0) = - \frac{1}{2} \cdot (x - (0))$

Simplify the equation and keep it in point-slope form.

$y + 0 = - \frac{1}{2} \cdot (x + 0)$

Step 6

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

Solve for $y$ .

Add $y$ and $0$ .

$y = - \frac{1}{2} \cdot (x + 0)$

Simplify $- \frac{1}{2} \cdot (x + 0)$ .

Add $x$ and $0$ .

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

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

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

Reorder terms.

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

Remove parentheses.

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