Transcript text: Use the given conditions to write an equation for the line in point-slope form and in slope-intercept form.
Passing through $(8,-7)$ and perpendicular to the line whose equation is $y=\frac{1}{2} x+5$
Write an equation for the line in point-slope form.
Solution
Solution Steps
Step 1: Determine the Slope
The slope of the new line is the negative reciprocal of the given line: \(m' = -2\).
Step 2: Use the Point-Slope Form
Using the point \((8, -7)\) and the slope \(m' = -2\), the point-slope form is \(y + 7 = -2(x - 8)\).
Step 3: Convert to Slope-Intercept Form
Rearranging the point-slope form to slope-intercept form gives \(y = -2.0x + 9\).
Final Answer:
The equation of the line that is perpendicular to the given line and passes through \((8, -7)\) is \(y = -2.0x + 9\).
