Question

I cant remember this its not a test but i have more questions can someone pleas help with a simple way of working it

Answer 1

Assume that your equation is such form
`y=mx+n` Now you must find what m and n are. Just try given points that are (x,y) = (0,-2), (1,4), (2,10), (3,16), (4,22) and (5,28) Only two of them enough to find what m and n are. I picked (0,-2), (1,4) and put them in equation. Let me show you.

For (0,-2) :
`-2=m.0+n` then I have
`n=-2` Now I must find m=?

I used (1,4) then
`4=m.1+ (-2)` (I know what n is) Hence I have m=6

Therefore your equation is
`y=6x-2` so ?=6 in picture.
