Question

determine if the lines 9x - 2y = 16 and 2x - 9y = -18 are parallel, perpendicular or neither

Answer 1

i think its neither but i need confirmation

Answer 2

can you tell me slopes of both lines ?

Answer 3

correct me if im wrong here but..... 2.5x and 2/9 x

Answer 4

make the expression into the form of y= mx +c. where c is a constant and m is the slope of the line. So for example 9x-2y=16.

9x-2y=16
2y = 9x-16
y= 9/2 x - 8

9/2 is the slope that line. Go ahead, Find the other.

Answer 5

@jonnyrules96 you sure about 2.5 ?
