Question

Determine whether the following two lines are parallel, perpendicular, neither, or both.
L1: passes through (5, 7) and (2, 8)
L2: passes through (0, 5) and (3, 4)

Answer 1

you need HOW or need ANSWER?

Answer 2

How would be nice so i can do it without help in the future

Answer 3

ok, you should find slope of lines that through from points, can you find it?

Answer 4

i believe it is perpendicular but im not certain

Answer 5

\[\frac{\Delta y}{\Delta x}\]for L1, it's\[\frac{8-7}{2-5}=-\frac{1}{3}\]and for L2 is\[\frac{4-5}{3-0}=-\frac{1}{3}\]so slopes are equal

Answer 6

so its parallel?

Answer 7

yup ;)

Answer 8

thanks!

Answer 9

yw ;)
