If I have Y=-3X+21 do i simplify or keep it just the same???
Answered by helper
y = 3x + 21 is in the slope-intercept equation form (y = mx + b).

This equation cannot be simplified. It's as good as it gets.

couldnt you simplify it to...

y = x + 7 ?

you have three x and 21 so to get one x divide both by 3. not sure if that's right but maybe!

It depends on what the problem asks for.

If the equation was,
3x + 21 = 0
3(x + 7) = 0
x + 7 = 0

But, the equation is y = 3x + 21.
If, the problem said to factor, this could be written as
y = 3(x + 7)

But, I don't know what her problem is looking for.
