Answer 1

I Think it A or C

Answer 2

consider any two points on the line.. locate their coordinates as (x1,y1) and (x2,y2)

Slope m = (y2-y1)/(x2-x1)

Answer 3

Take the two points and plug them into the slope formula.

(-5, 4) and (4, -2)

\(m = \dfrac{y_2-y_1}{x_2-x_1}\)

Where \(y_2 = -2\), \(y_1 = 4\), \(x_2 = 4\), and \(x_1 = -5\)

Plug them in:

\(m = \dfrac{-2-4}{4+5}\)

Can you simplify that? @tiffany__

Answer 4

No

Answer 5

Just subtract -2 - 4, then add 4 + 5.

Answer 6

Tell me what you get.

Answer 7

2 10

Answer 8

Huh?

Subtract -2 - 4, tell me what you get.

Answer 9

-6

Answer 10

Yes, now add 4 + 5

Answer 11

9

Answer 12

Yep, that gives us -6/9, which simplifies to -2/3.

Answer 13

thank you

Answer 14

No problem.
