    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.

      Mr Mac
