well hannah all you need do is substitute for the 3 values of x in the equation to find values of y
hlambach
  • hlambach
Yeah, what welshfella said...
welshfella
  • welshfella
for example put x = -15 into a + y = 6 -15 + y = 6 add 15 to both sides y = 6 +15 = 21 so we know that either b or c are the correct options as a has (-15,-21) so next try x = -6
anonymous
  • anonymous
so is it b or c?
welshfella
  • welshfella
yes - to find out which try plugging in the next value of x which is -6 and see what you get
welshfella
  • welshfella
all you have to do is replace the x in x + y = 6 with -6 and work out what y is

uhm... is still don't understand, but ok.
welshfella
  • welshfella
-1 + y = 6 now solve for y
anonymous
  • anonymous
y=7
welshfella
  • welshfella

welshfella
  • welshfella
