Find the Perpendicular Line Passes through (4,1) Perpendicular to y=2/3x+11

Passes through $(4, 1)$ Perpendicular to $y = \frac{2}{3} x + 11$

Find the slope when $y = \frac{2}{3} x + 11$ .

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.

$y = m x + b$

Simplify the right side.

Combine $\frac{2}{3}$ and $x$ .

$y = \frac{2 x}{3} + 11$

Reorder terms.

$y = \frac{2}{3} x + 11$

Using the slope-intercept form, the slope is $\frac{2}{3}$ .

$m = \frac{2}{3}$

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

$m_{perpendicular} = - \frac{1}{\frac{2}{3}}$

Simplify $- \frac{1}{\frac{2}{3}}$ to find the slope of the perpendicular line.

Multiply the numerator by the reciprocal of the denominator.

$m_{perpendicular} = - (1 (\frac{3}{2}))$

Multiply $\frac{3}{2}$ by $1$ .

$m_{perpendicular} = - \frac{3}{2}$

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

Use the slope $- \frac{3}{2}$ and a given point $(4, 1)$ 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 $m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ .

$y - (1) = - \frac{3}{2} \cdot (x - (4))$

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

$y - 1 = - \frac{3}{2} \cdot (x - 4)$

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

Solve for $y$ .

Simplify $- \frac{3}{2} \cdot (x - 4)$ .

Rewrite.

$y - 1 = 0 + 0 - \frac{3}{2} \cdot (x - 4)$

Simplify terms.

Apply the distributive property.

$y - 1 = - \frac{3}{2} x - \frac{3}{2} \cdot - 4$

Combine $x$ and $\frac{3}{2}$ .

$y - 1 = - \frac{x \cdot 3}{2} - \frac{3}{2} \cdot - 4$

Cancel the common factor of $2$ .

Move the leading negative in $- \frac{3}{2}$ into the numerator.

$y - 1 = - \frac{x \cdot 3}{2} + \frac{- 3}{2} \cdot - 4$

Factor $2$ out of $- 4$ .

$y - 1 = - \frac{x \cdot 3}{2} + \frac{- 3}{2} \cdot (2 (- 2))$

Cancel the common factor.

$y - 1 = - \frac{x \cdot 3}{2} + \frac{- 3}{2} \cdot (2 \cdot - 2)$

Rewrite the expression.

$y - 1 = - \frac{x \cdot 3}{2} - 3 \cdot - 2$

Multiply $- 3$ by $- 2$ .

$y - 1 = - \frac{x \cdot 3}{2} + 6$

Move $3$ to the left of $x$ .

$y - 1 = - \frac{3 x}{2} + 6$

Move all terms not containing $y$ to the right side of the equation.

Add $1$ to both sides of the equation.

$y = - \frac{3 x}{2} + 6 + 1$

Add $6$ and $1$ .

$y = - \frac{3 x}{2} + 7$

Reorder terms.

$y = - (\frac{3}{2} x) + 7$

Remove parentheses.

$y = - \frac{3}{2} x + 7$
