Question

Find the slope of the line containing the given points.
(2, 3), (5, 6)

Answer 1

Do you know the formula for the slope of a line?

Answer 2

the steps work better for me

Answer 3

subtract one point from the other and stack the ys/xs

Answer 4

@jabberwock i believe its rise over run . .

Answer 5

Right. Which coordinate represents the rise?

Answer 6

*x or y*

Answer 7

x

Answer 8

x goes left and right, and y goes up and down. So the "rise" refers to a change in the y-coordinates, and the "run" refers to a change in the x-coordinates.

Answer 9

What are your two y-coordinates?

Answer 10

3,6

Answer 11

Good, so subtract one of those from the other.

Answer 12

3-6=?

Answer 13

3

Answer 14

-3

Answer 15

Good :)

Answer 16

-3 right

Answer 17

Now the x-coordinates.

The only thing you have to keep in mind in finding the slope is that you need to keep the coordinates in the same order.

The first y-coordinate you used was 3, which was part of the point (2, 3). This means you need to calculate 2-5 (instead of 5-2)

Answer 18

Does that make sense?

Answer 19

So you have -3/-3, which is equal to +1

Answer 20

rise/run

Answer 21

Or would it be easier if i use the formula \[y-y_1=m(x-x_1)\]
