Question

Which equation would you use to find out if the two lines in the graph are parallel?

Answer 1

A.

Answer 2

B.

Answer 3

the slope of parallel lines are the same

Answer 4

m= slope/ gradiant -- same thing
\[m=\frac{y_2-y_1}{x_2-x_1}\]

Answer 5

substitute the values for slope
set them equal to each other
then determine which multiple choice looks like your answer

Answer 6

is it A

Answer 7

Does -1 = + 1 ?
That would be what A. is saying!!

Answer 8

OH

Answer 9

Is there a C. ?

Answer 10

I ask because B. is saying -1 = +2 Another falsehood!!

Answer 11

If A. and B. is all you got the answer is : "neither one"

Answer 12

I like that one it says 1 = 1 and that just happens to be the slope of those lines.

Answer 13

That is actually what @completeidiot was telling you with the slope formula.

Answer 14

which one

Answer 15

parallel lines have equal slope. The one with slope of 1 = 1

Answer 16

The one that has 3/3 =2/2
1 = 1
