Question

3x+4y=7_4x+3y=10 are these lines perpendicular,parallel, or neither

Answer 1

x = 19/7, y = -2/7

Answer 2

neither because the slope is not the negative reciprocal
both have negative slopes and the other has to be positive to be perpendicular, and they have to be the exact same to be parallel

Answer 3

thank you

Answer 4

I probabably should have punctuated that better.

Neither because the slope is not the negative reciprocal.
Both have negative slopes. The equations have to be the exact opposite to be perpendicula like m=-1/2 and m=2/1 to be perpendicular, and they have to be the exact same to be parallel m=-1/2 and m=-1/2
