Question

Help!!!!! Write an equation of the line that passes through the point (1,2) and
has the slope, m = 2.


I got Y=2X but it wasn't right.

Answer 1

You need to use the point slope formula.
\[y-y _{1}=m(x-x _{1})\]
Where the point given represents \[(x _{1}, y _{1})\] and m is slope.

Answer 2

I don't get it

Answer 3

Do you know how to use formulas?

Answer 4

I'm not good

Answer 5

Ok, so you want to take what you have and decide what it will represent in your formula so that you can put it into your formula.
So the point given is going to be the \[(x _{1}, y _{1})\]
What are those two values?

Answer 6

I don't know ? /:

Answer 7

What is the point that is given to you in the problem?

Answer 8

to use the m for the slope or somthing

Answer 9

Points are given to you as two numbers inside of parenthesis with a comma separating them. Can you find that in the problem?

Answer 10

The answer of y = 2x is correct. It has the slope of 2 and it goes through (1,2)

y = 2x

2 = 2*1 ... plug in (x,y) = (1,2)

2 = 2

So this shows that y = 2x goes through (1,2)

Answer 11

So you might have to write the answer in standard form or point slope form

Answer 12

Well what I had put was not right

Answer 13

So try 2x - y = 0 which is what you'd get if you convert to standard form

Answer 14

I put 2x - y = 0 as the answer?

Answer 15

yeah try that

Answer 16

Thank you

Answer 17

so that worked?

Answer 18

I have other answers I have to redo , and then I can re submit my test :)

Answer 19

ok glad it worked, i wish they explicitly stated they wanted the answer in standard form, but oh well

Answer 20

haha yeah I know

Answer 21

Think some. o.o
