What if a line passes through the origin and it has to be parallel to x + y = 10

Question

anonymous · Answer

What can you say about the slope of two parallel lines?

anonymous · Answer

That they are the same

anonymous · Answer

Ok , can you determine the slope of x + y = 10?

anonymous · Answer

No I cant

anonymous · Answer

Slope-Intercept Form is 

y=mx+b 

where m is the slope

sample 

2x + y = 3                       you will solve for y in terms of x, so this will become
        y = -2x + 3

so the slope in this example is -2.

can you do it now?

K

anonymous · Answer

Is it -y = x + 10?

anonymous · Answer

check it again .. x + y = 10 ----- >

Once you find the slope of that equation, everything else is pretty simple. It is asking for an equation through the origin, meaning (0, 0) 
So use:
$$y-y_{1}=m(x-x_{1})$$

luigi0210 · Answer

In slope-intercept form, the y can not be negative

anonymous · Answer

Oh k

luigi0210 · Answer

So the equation you had was okay, it just needed to be multiplied by a -1.

anonymous · Answer

No it's not, its should be -10 if that's the case.

anonymous · Answer

Y?

luigi0210 · Answer

What? -10?

anonymous · Answer

cos you said his equation was ok, just multiply by -1, i don't think so

luigi0210 · Answer

Oh, I see what you mean. 
Yea, show us your final answer @hubbabubba for the equation
