Write an equation for each line:

through (-1,3) and parallel to y=2x+1

I know that the slop will be 2 because it is parallel.

If m=2 then used the same equation for the point (-1,3)

3=2(-1)+ b

Now find b

Finally write the equation

You can take it from here. I you don't get it, post it.

Thank-you. I got -1=b, but I'm not sure how to put it in standard form. Like what should be the A and B?

standar form is

y=mx+b

you know m and you know b, that is all you need...

y=?x+?

That's not standard form, that's slope-intercept form. Standard form is Ax+By=C

anyone please?

If you have the line in point-slope form

y=mx+b then

-mx+y=b will still be in the form

Ax+By=C

If you divided by B you'd have

(A/B)x+y=(C/B) so you should be able to see what the A, B and C are.

sorry about the time...if you still need to find the answer, try this:

If parallel to y=2x+1 it means they have the same slope m=2 and you know it goes thru point (-1,3) so 3=(2)(-1)+5 then

y=2x+5. all you need now is to put it in standard form. A and B are the coefficients of variables.

general form: -2x+y=5

find the equation of the line which has a slope of 3/4 and contains the point (0,3).
