Question

Calculate the slope of the points (-2, -1) and (3, 4).


a. 1

b. 2

c. 3

d. 4

Answer 1

Slope Formula

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

Answer 2

Plug in and solve. :)

Answer 3

(x, y) <-- for reference

Answer 4

so its B?

Answer 5

Not quite, try calculating again.

Answer 6

\[\frac{ 4 - (-1) }{ 3 - (-2) }\]

Answer 7

- ( - just turns into + so

\[\frac{ 4 + 1 }{ 3 + 2 }\]

Answer 8

that would be 5?

Answer 9

Both of them would be 5, so now divide

Answer 10

What happens when you divide a number by itself?

Answer 11

you get 1

Answer 12

=)

Answer 13

So just remember that formula and calculating slope with only two points should be easy.

Answer 14

so its a?

Answer 15

yeap

Answer 16

cool thanks!
