Help

Answer 1

2 points

\[\large slope = \frac{y_2 - y_1}{x_2 - x_1}\]

Answer 2

So we have the 2 points...

(1 , 1) and (-6 , 8)
(x1,y1) (x2 , y2)

So we plug those into the equation

\[\large slope =\frac{8 - 1}{-6 - 1} = \frac{7}{-7} = ?\]

Answer 3

-1

Answer 4

thank you!

Answer 5

Anytime :)

Answer 6

@johnweldon1993

Answer 7

When we have an infinite slope (vertical line) we have an undefined slope

Answer 8

Negative uh?

Answer 9

so yes negative :)

Answer 10

Thank you!

Answer 11

Answer 12

it gon be positive right

Answer 13

Perpendicular lines have negative reciprocal slopes

Meaning...if you multiply the slopes of both the lines...it should be - 1

And yes it will be positive

Answer 14

Lol ...so in this case...

negative reciprocal means flip the number...and then turn it negative (or change the sign)

-5 will become -1/5

And negative would mean it is then 1/5

Answer 15

So if the slope of that green one is -8

We will need the negative reciprocal of that....

so flip the number \[\large -8 = -\frac{8}{1} \rightarrow -\frac{1}{8}\]

And change the sign of it... \(\large \frac{1}{8}\)

Answer 16

Parallel lines = same slope :)

Answer 17

why you so smart_______- lol

Answer 18

Lol idk :P and same thing here...same slope = parallel

Answer 19

Its a vertical line again..so undefined :)
