Answer 1

(1,0) and (5,5)

Answer 2

Answer 3

First you need to find the slope

Answer 4

5/4

Answer 5

Okay. Now choose one of the plug it in to the point-slope formula

Answer 6

one of the points*

Answer 7

can you show me? so i can use this as a base for the rest of the problems

Answer 8

y-y1=m(x-x1)

Answer 9

thats the formula

Answer 10

i know the formula

Answer 11

y-5=5/4(x-5)

Answer 12

so, once i find the slope, i can choose any of the points i want and just plug them into the formula? and i dont have to use them all?

Answer 13

Yes, thats correct. No you do not, but only plug numbers into x1/y1 never into x/y

Answer 14

can i post another one here and you can see if i do it right?

Answer 15

yes

Answer 16

(-4,10) and (-6,15)

Answer 17

label x1 y1 and x2 y2...

Answer 18

slope is 5 over -2?

Answer 19

It is

Answer 20

okay, so the formula is y-y1=m(x-x1)

Answer 21

so would y-10=5/-2(x-15) be an answer?

Answer 22

No, you have to only use one point. Let's use (-4,10) x= -4 and y=10, so now use this and plug in.

Answer 23

y-10=5/-2(x-(-4)?

Answer 24

Remember two negative cancel each other out and it turns into a positive. So in this case it would be x+4

Answer 25

right. but that would work?

Answer 26

yes, it would

Answer 27

thanks bae
