Question

What is the equation in standard form of the line which passes through (–2, –3) and has a slope of

Answer 1

of ...

Answer 2

so standard form is
y= mx +b

Answer 3

m will be your slope..
if we have a slope and two points we can use them to find b

Answer 4

1/2

Answer 5

okay so now we have y=(1/2)x +b

Answer 6

whats is one of your y's equal to?

Answer 7

and what about one of your x's?

Answer 8

I thought standard form is a(x)+b(x)=c

Answer 9

ahh yes you are right

Answer 10

yeah I don't know how to do this at all

Answer 11

okay we can still use what we have done

Answer 12

so y=(1/2)x +b
and since we know that at one point y=-3 and x=-2 we can plug those in to find b

Answer 13

-3= (1/2)(-2) +b
-3=-1 +b
-2 = b

Answer 14

thats our b for all points

Answer 15

y=(1/2)x -2

Answer 16

that's what I ended up with but what would it be in standard form?

Answer 17

now just move the x term over

Answer 18

y - (1/2) x =-2

Answer 19

here's the answers I was given..
2x + y = 4

2x – y = 4

x + 2y = 4

x – 2y = 4

Answer 20

we can simplfy our answer to look like theres if you would like, just multiply every term by -2

Answer 21

damn really..I didn't even think of that thank you so much!

Answer 22

yes i guess they are a little picky with that x term being positive... so you should always do that at the end

Answer 23

no problem... math is easy once ya get it!
