Question

if two lines are parallel which statement must be true

Answer 1

A.the two lines have opposite slopes

B. the two lines have the same slope

C. the two lines have zero slopes

D. the two lines have undefined slopes

Answer 2

need help please

Answer 3

parallel lines ALWAYS have the same slope

example:

y = 3x + 5
y = 3x + 9

these two lines have the same slope of 3. They have different y intercepts which mean they never ever cross each other.

Answer 4

something like y = 2x+5 (slope is 2) and y = 7x + 12 (slope is 7) have different slopes so they will eventually cross at some point. The fact that they cross means they aren't parallel

Answer 5

thanks
