Line r has a slope of 8/5 .Line s is perpendicular to r.What is the slope of line s? Simplify your answer and write it as a proper fraction, improper fraction, or integer. _____

Identify Perpendicular Relationship: Line s is perpendicular to r, so we need the opposite reciprocal of r's slope.Calculate Slope of Line r: Slope of line r: 8/5.Find Reciprocal with Opposite Sign: Reciprocal of 8/5 is 5/8, but we need the opposite sign.Determine Slope of Line s: So, the slope of line s is -5/8.

Full solution

Q. Line

r

has a slope of

\frac{8}{5}

. Line

s

is perpendicular to

r

. What is the slope of line

s

Identify Perpendicular Relationship: Line $s$ is perpendicular to $r$ , so we need the opposite reciprocal of $r$ 's slope.
Calculate Slope of Line r: Slope of line r: $\frac{8}{5}$ .
Find Reciprocal with Opposite Sign: Reciprocal of $\frac{8}{5}$ is $\frac{5}{8}$ , but we need the opposite sign.
Determine Slope of Line $s$ : So, the slope of line $s$ is $-\frac{5}{8}$ .
