Solution Steps

Step 1: Find the Slope of Line Segment RH \overline{RH}

To find the slope of the line segment RH \overline{RH} with endpoints R(4,4) R(-4, 4) and H(2,4) H(2, -4) , we use the slope formula:

m=y2y1x2x1 m = \frac{y_2 - y_1}{x_2 - x_1}

Substituting the given points:

m=442(4)=86=43 m = \frac{-4 - 4}{2 - (-4)} = \frac{-8}{6} = -\frac{4}{3}

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 \overline{RH} is:

m=143=34 m_{\perp} = -\frac{1}{-\frac{4}{3}} = \frac{3}{4}

Step 3: Write the Equation of the Perpendicular Line

We use the point-slope form of the equation of a line, which is:

yy1=m(xx1) y - y_1 = m(x - x_1)

Given the point (3,1) (3, -1) and the slope 34 \frac{3}{4} :

y(1)=34(x3) y - (-1) = \frac{3}{4}(x - 3)

Simplifying, we get:

y+1=34(x3) y + 1 = \frac{3}{4}(x - 3)

Final Answer

y+1=34(x3) \boxed{y + 1 = \frac{3}{4}(x - 3)}
