Answer:
yes, EF || GH
Step-by-step explanation:
Using the slope formula, we can compare the slopes of EF and GH.
m = (y2 -y1)/(x2 -x1) . . . . . slope of segment between (x1, y1) and (x2, y2)
Slope of EF is ...
m = (1 -5)/(7 -2) = -4/5
Slope of GH is ...
m = (5 -(-3))/(-8 -2) = 8/-10 = -4/5
The slopes of the segments are the same, so they are parallel.
