SOLUTION: Determine whether the lines are parallel, perpendicular, or neither. Line 1 passes through (0, 3) and (2, 5) Line 2 passes through (5, -4) and (-3, 3)

Question 771455: Determine whether the lines are parallel, perpendicular, or neither.
Line 1 passes through (0, 3) and (2, 5)
Line 2 passes through (5, -4) and (-3, 3)

Answer by Cromlix(4381) (Show Source): You can put this solution on YOUR website!
Line 1)
Gradient = y2-y1/x2-x1
Gradient = 5 - 3/2 - 0
Gradient = 2/2 = 1
Line 2)
Gradient = y2-y1/x2-x1
Gradient = 3 -(-4)/-3 - 5
Gradient = 7/-8
For two lines to be parallel
gradients must equal one another
m1 = m2
For two lines to be perpendicular
to one another, their gradients
must multiply together to give -1
m1*m2=-1
These lines are neither parallel or
perpendicular.
Hope this helps.
