Transcript text: Question 5 Line segment $R H$ has endpoints $R(-4,4)$ and $H(2,-4)$. Which equation represents a line perpendicular to $\overline{R H}$ that passes through the point $(3,-1)$ ?
Solution
Solution Steps
Step 1: Find the Slope of Line Segment RH
To find the slope of the line segment RH with endpoints R(−4,4) and H(2,−4), we use the slope formula:
m=x2−x1y2−y1
Substituting the given points:
m=2−(−4)−4−4=6−8=−34
Step 2: Determine the Slope of the Perpendicular Line
The slope of a line perpendicular to another line is the negative reciprocal of the original line's slope. Therefore, the slope of the line perpendicular to RH is:
m⊥=−−341=43
Step 3: Write the Equation of the Perpendicular Line
We use the point-slope form of the equation of a line, which is:
