Question

Decide whether the pair of lines is parallel, perpendicular, or neither.

9x + 3y = 12 and 12x + 4y = 17

Answer 1

well you can put the two in slope intercept form and decide from the slopes

Answer 2

parallel the coefficient is -3 in front of x

Answer 3

thank you

Answer 4

set them up in y=mx+b form

Answer 5

parallel!

Answer 6

3y=-9x+12
y=-3x+4, m=-3

4y=-12x+17
y=-3x+17/4, m=-3

Parallel, like johnnybreuer said.

Answer 7

sorry
its parallel
\[\frac{a1}{a2}=\frac{b1}{b2} \neq \frac{c1}{c2}\]
