Fitting Linear Models to Data · Exercise 103

Determine whether the lines given by the equations below are parallel, perpendicular, or neither parallel nor perpendicular.

Given below are descriptions of two lines. Find the slopes of Line 1 and Line 2. Is the pair of lines parallel, perpendicular, or neither?
Line 1: Passes through $\left(-2,-6\right)$ and $\left(3,14\right)$
Line 2: Passes through $\left(2,6\right)$ and $\left(4,14\right)$

Its source prints no answer for this problem, so there's nothing to check against.
