students couldn't draw the line for equation y = x + 2.
I have to say that 30 something years later I don't even understand the question so as for the answer, who knows.
I always that that ' if 2y=x and 10x =9b then what is m+z ' to be the most pointless exercise and personally I have never needed to know the answer since leaving school.
But I do accept some find it useful ( 5 % ? )
