text: Slope is based on Rise (Y) over Run (X)...\n\nThe equation specifically is (Y2-Y1) divided by (X2-X1) so...\n\n(5-3)=2 divided by (4--2)=6 equaling 1/3\n\nSince the lines are parallel to this equation, they will all have the same slope of 1/3 with different Y-Intercepts!\n\nIf you were finding the perpendicular you would find the Negative Inverse, which would be -3 slope for these points!
