Transcript text: Find an equation for the line with the given properties. Express your answer using either the general form or the slope-intercept form of the equation of a line.
Perpendicular to the line $y=\frac{1}{3} x+1$; containing the point $(-1,3)$
The equation is $\square$
(Type an equation. Simplify your answer.)
Solution
Solution Steps
Step 1: Find the slope of the perpendicular line
To find a line perpendicular to the given line \(y = 0.3333333333333333x + 1\), we use the negative reciprocal of \(m\).
The slope of the perpendicular line, \(m'\), is \(-\frac1{0.333}\) = -3.
Step 2: Use the point-slope form to find the equation of the perpendicular line
Using the point \((-1, 3)\) and the slope \(m' = -3\), we apply the point-slope form:
\(y - 3 = -3(x + 1)\)
Simplifying to the slope-intercept form \(y = mx + b\), we solve for \(y\):
\(y = -3.0x + 0\)
Final Answer:
The equation of the line perpendicular to \(y = 0.3333333333333333x + 1\) passing through \((-1, 3)\) is \(y = -3.0x + 0\).
