Question

Which pair of lines is parallel?


y = 4x + 1 and y = 4x =5
y = -2x and 2y - 2x = -2
y = 1/4x + 2 and y -2= 1/2x
y = 1/5x + 1 and 5y _ x = 10

Answer 1

You can tell that 2 lines are parallel if their slopes have the same magnitude

Answer 2

first one

Answer 3

parallel lines will have the same slope, so just find the slopes of these equations and see which ones are the same

Answer 4

How do you find the slope of equations?

Answer 5

P13...you need to stop just giving answers without explaining

Answer 6

if the equations are in y = mx + b form, the m position is the slope

for example : y = 4x + 1
the number in the m position is 4, so the slope is 4

if it is not in y = mx + b form, you need to put it into y = mx + b form
for example : y - 2 = 1/2x -- add 2 to both sides
y = 1/2x + 2 ...the slope here is 1/2

does that make sense to you ?

Answer 7

Yes thank you!

Answer 8

no problem...glad to help :)
