Question

how can i tell if the following two lines are paralell, perpendicular or neither?
6x+3y=5 and -x+2y=6

Answer 1

good question...simplify the equations such that y has no coefficients

Answer 2

^that is the first step

Answer 3

6x + 3y = 5
3y = -6x + 5
y = -6/3x + 5/3
y = -2x + 5/3
do this for the other one.

Answer 4

parallel meaning they have the same gradient, perpendicular meaning that the gradient of both lines have to times together to equal -1 or neither is which is just if their not parallel or perpendicular.

Answer 5

still confused here
