how can i help you???? :) :)

Answer 9

uh well the line is vertical so it should be undefined

Answer 10

horizantal zero
vertical undefined

Answer 11

Is it true that the line containing points(4, -7) and (4, 8) doesn't have defined slope?
How can you solve it?

Answer 12

slope formula

Answer 13

it is true

Answer 14

what is slope formula?

Answer 15

you cannot divide by zero

Answer 16

(y1-y2)/(x1-x2)

Answer 17

first of all slope intercept formula is
so plug that into the formula
