From Sara: The question is:
Write the equation of a line that is parallel to y=3x2 through the point (5,9).
I think the correct equation for this is y=3x+24.
But I have to write it in standard form, and I can't seem to figure out how to do that. Please answer soon! Thanks! Answered by Stephen La Rocque and Penny Nom. 





yintercept form

From Ken: Simple way on how to convert to & from yintercept form & Std. form.
Eg: Convert into yintercept form: 3x+4y+7=0,
Eg.: Convert into Std. Form: y=1/2x +3, y=50x +300. I would appreciate your
help in this matter, as I find it hard to understand.
Kind Regards: Ken Answered by Penny Nom.
