Answer 9

(x1,y1) = (3,2)
(x2,y2) = (0,-3)

use the slope formula

\[\Large m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\]

to find the slope

Answer 10

i was never taught this though

Answer 11

@jim_thompson5910

Answer 12

subtract the y coordinates
subtract the x coordinates
make sure you subtract in the same order

then divide the two differences (y diff over x diff)

Answer 13

what? i dont get it
@jim_thompson5910

Answer 14

what are the y coordinates of these two points

(3,2) and (0,-3)

Answer 15

ive never done that before

Answer 16

hmm perhaps you're in a lesson that the teacher hasn't gotten to yet?

Answer 17

its a scantron upf\date and ive never been taught that. my teaccher said to find help on the internet. are you supposed to learn this is 6th gradr?

Answer 20

if the teacher didn't get to this part, then I don't see how it's fair she expects you to know this material

Answer 21

b ?

Answer 22

anyways, the y coordinates of (3,2) and (0,-3) are 2 and -3, agreed?

Answer 23

yes i think

Answer 24

is it b

Answer 25

subtract the y coordinates

2 minus (-3) = 2 - (-3) = 2+3 = 5

Answer 26

what are the x coordinates of the two points?

Answer 27

dont know im going to guess
