Question

*MEDAL*

Graph this:

-5x + 2y = 2

Answer 1

Put it in the form y = mx + c

where m would be a number times x (the gradient) and c would be point on which the graph intersects the y axis.

Answer 2

Here's my choices:

Answer 3

I'll tell you which one is right if you have a go!

Answer 4

It would have to be the 2nd or 4th one,r ight?

Answer 5

Answer 6

It couldn't be the second one, try rearranging it, you'll see it straight away

Answer 7

Hmm...

Answer 8

Is it the 3rd one?

Answer 9

y=(2+5x)/2 right?

Answer 10

right.

Answer 11

So that simplifies to?

Answer 12

3.5x?

Answer 13

y = (5/2) x + 1

Answer 14

2.5x + 1...?

Answer 15

Yes, so the graph has to cross the y axis at 1, which one of your diagrams crosses the y axis at 1?

Answer 16

Its the first one I think...

Answer 17

The 1st one, yes.

Answer 18

Yeah, it's the first one :)

Answer 19

Thanks, dmot! :D
