Which pair of lines in the image is
perpendicular?

since you got no image, i will define a perpendicular lines. a perpendicular lines are lines that make right angles (always 360^o), i will put an image to show you what perpendicular lines look like.

hope this you!

(btw, this is the same answer as the other question and i copied my answer and pasted it here so mods, i did not plagarize, i copied my answer from another question (same

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
