Are the following lines parallel, perpendicular, or neither?
L1 through (–4, –7) and (1, 3)
L2 through (2, 6) and (4, 10)

They are parallel. The slope of L1 = (3-(-7))/(1-(-4)) = 2.
The slope of L2 is (10-6)/(4-2) = 2. Since they have the same slope, they are parallel.

L1 with equation x + 2y = 4 L2 with equation 2x + 4y = 5 placed each equation in slope-intercept form: y = mx + c. If m is the same for each line, then the strains are parallel. If both values of m multiply mutually to furnish -a million, then the strains are perpendicular. in the different case they're neither.

slope of line 1
(3-(-7)/(1-(-4))= 10/5=2
lope of line 2
(10-6)/(4/2)= 4/2=2
the lines are parallel

draw it out on a piece of grid paper or draw it in paint and see. draw x axis and draw y axis and then plot the points yourself!!!
you lazy bum...
hint=(parallel)
