Question

8. which of the following equations is parallel to the line passing through A(-2, 7), B(-2,-2)

Answer 1

y=-2
y=x
3x=5
-2x=7y

Answer 2

Ok, the lines that are paralyses to each other always have the same slope.

Answer 3

parallel, I meant.

Answer 4

ok

Answer 5

find the slope of the line that has points (-2, 7) (-2,-2) by plugging them into the slope formula, do you know the slope formula?

Answer 6

I got y=-2 but I feel like it's wrong?

Answer 7

hold on, that can't be, b/c that has no slope, it is a vertical line.

Answer 8

Draw a sketch.

Answer 9

ya m= y1-y2/x1-x2

Answer 10

can you find the slope of the line that passes through (-2, 7) and (-2,-2)

just plug these points into the slope formula.

Answer 11

Understood?

Answer 12

ya wait though

Answer 13

the slope is undefined, b/c it is a vertical line. sorry.

Answer 14

if you plug the points into slope formula you will also see that.

Answer 15

that's what i thought. i was like the didnt ask me for the slope

Answer 16

Yeah, that was my bad!

Answer 17

there is no slope.
