Question

line contains points (2, -2) and (-4, 1). Another line graphed in the same coordinate plane contains points (1, 2) and (-3, 4). Based on the slopes of these lines, are they parallel, perpendicular or neither?

parallel
perpendicular
neither

Answer 1

m1= (1+2)/(-4-2)=-0.5
m2=(4-2)/(-3-1)=-0.5
The slopes are the same therefore they are parallel

Answer 2

thank you!!!
