Question

What is the equation of the following line written in general form? (The y-intercept is -1.)

2x + y - 1 = 0
-2x - y - 1 = 0
2x - y - 1 = 0

Answer 1

so first you have to find the slope do you know how to do that?

Answer 2

how?

Answer 3

lol online school dosnt teach me pellet ughh

Answer 4

look at this http://www.purplemath.com/modules/slope/slope02.gif

Answer 5

so you pic 2 points on the line you already have (1,1) so pick another point i chose (-1,-3) and plug in the two y's and the 2 x's and it looks like this

Answer 6

1+3
------
1+1


that simplifies to

4
---
2

then that turns to just 2 because 4 divided by 2 is simply 2.

Answer 7

so now you have you slope intercept form of the equation which is y=2x-1 so to convert that to general form you would have to move the y over to the other side and it would look like this and thats your answer.

2x-y-1=0

Answer 8

so the last

Answer 9

how are you so good at this tester

Answer 10

this is alg 1 right? so i was great at that but alg 2 is a bit tricky so pay good attention this year ^_^

Answer 11

kk lol
