Hello sir, a was revising for the test using the revision sheets and need help , forgot how to do questions 3 and 13 on revision sheet 1 , sorry it’s at last minute this wouldn’t let me on the blog and that’s me just got it to work.

No problem at all Casey, don’t worry too much about Q3. We covered all the changing subject stuff we need when we rearranged the equations of a straight line.

Q13 is simply subtitution so for the first entry on the bottom row you have;

y=2x+2 and if we sub in x =-2 then we get y= 2 x (-2) + 2 OR y = 2 times -2 + 2 = -4 + 2 = -2

Let me know if that helps.

Aw yeah a can remember now , thankyou!

a was off on Monday so will I do the b or the c test tomorrow?

You will sit the C test with everyone else Ewan.

Is the reversion 1c the best one to use to revise ?
