Question

What is the equation of the line that passes through the points (-2, 1) and (1, 10)?

3x - y = -7

3x - y = -5

3x - y = 5

x + 3y = -5

Answer 1

what is the slope?

Answer 2

(10-1)/(2-(-1))

Answer 3

@shutupron ?

Answer 4

9 and 1

Answer 5

there isnt a slope?

Answer 6

slope = (10-1)/(2-(-1)) = ?

Answer 7

-7

Answer 8

?

Answer 9

what is 10-1?

Answer 10

9

Answer 11

what is 2-(-1)?

Answer 12

3

Answer 13

what is 9/3?

Answer 14

3

Answer 15

ok slope = 3

Answer 16

so y=mx+b = 3x+b
now we need to find b
use the point (1,10)
x=1 y = 10
10=3(1)+b
what is b?

Answer 17

3

Answer 18

10=3+b
what is b?

Answer 19

you might need to back track and learn some basics.

Answer 20

10=3+b

Answer 21

what is b?

Answer 22

if you have 3 apples and I give you some more apples and you now have 10 apples, how many apples did I give you? @shutupron

Answer 23

7

Answer 24

yes, so your equation is y=3x+7

Answer 25

so a?

Answer 26

3x-y=5

Answer 27

I said it was A because thats the closest one to your answer !

Answer 28

it says -7 not 7

Answer 29

sorry -7 lol yes a

Answer 30

thank you hahah
