A line has slope $\dfrac{2}{3}$. What is the slope of a line perpendicular to it?

Are the lines $y = 4x + 2$ and $y = 4x - 9$ parallel, perpendicular, or neither?

Write the equation of the line through $(0, 3)$ parallel to $y = -2x + 5$.

Find the distance between $(2, 1)$ and $(5, 5)$.

Find the exact distance between $(0, 0)$ and $(2, 6)$.

Find the midpoint of the segment from $(1, 2)$ to $(7, 10)$.

The midpoint of $AB$ is $(5, 3)$ and $A = (1, 1)$. What is $B$?

What fraction of the way from $A$ to $B$ is the point that partitions the segment in the ratio $1:3$ from $A$?

Partition the segment from $A(0, 0)$ to $B(8, 16)$ in the ratio $1:1$. What point results?

Two lines have slopes $3$ and $-\dfrac{1}{3}$. They are:

A triangle has vertices $(0, 0)$, $(6, 0)$, and $(0, 8)$. It is a right triangle because:
