Question

Line EF passes through the points (0, 1) and (3,3). Line GH passes through the points (3, -3) and (6, -1). These lines are A) skew. B) parallel. C) concurrent. D) horizontal.

Answer 1

Parallel, They have the same slope.

Answer 2

m1 = (3-1)/(3-0) = 2/3

m2 = (-1+3)/(6-3) = 2/3

m1 is the slope of EF and m2 is the slope of GH

m1 = m2

then the answer is B. parallel
