Homework Help: Maths

Posted by Nat on Tuesday, January 27, 2009 at 2:41am.

Just need a bit of help understanding what exactly i have to do here to work this out.

Rearrage the following equation and hence state the gradient and the y-intercept.

2y = 8x + 10

Do i just go:
y = mx + c
2y = 8x + 10
y = (8x + 10) /2
y = 4x + 5

or do i have to rearrange it so that it is stated in a different way?

Please help.

You have rearranged it perfectly into
y = mx + b form,
just by dividing both sides by two.

m (which is 4) is the slope and b (which is 5) is the y-intercept.
