Question

how do you find out if lines are parallel, perpendicular, or neither?

ex:
9x+3y=6
3x+9y=6

Answer 1

convert the line inti the form Y=mX+c
m=gradient
if the gradient of both line is same then they are parallel
if the gradient of L1 x the gradient of L2=-1 they are perpendicular

Answer 2

gradient=slope i knw that sir

Answer 3

he meant that for me lol.
so i have to change both the lines into y = mx + b?

Answer 4

not trying to be mean but considering the question saying gradient is confusing since you don't learn that till college

Answer 5

yes

Answer 6

convert to Y=mX+c
