Question

Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.

y = –3x + 7

–2x + 6y = 3

Choose the correct answer:

parallel
perpendicular
neither

Answer 1

the slope of \(y=mx+b\) is \(m\)
the slope of \(y=-3x+7\) is ?

Answer 2

the slope of \(ax+by=c\) is \(-\frac{a}{b}\)
the slope of \(-2x+6y=3\) is ?

Answer 3

Answer 4

am I correct?

Answer 5

You get the slopes 3 and -1/3. You see that they are not equal and therefore the lines aren't parallel, but what about perpendicular?
