Because of the one they solve in the class is
Y=a+b+X square where a and b constant Y =a+bx square is the relationship between y and x square 11=a+b(1) square 5=a+b(2) square 11=a+b 5= a+4b subtract equation (3) from (4) 5-11=a-a+4b-b -6 divide 3 =-2 substitute -2 for b in (3) after solving that they bring out the relationship between them
1 answer
The relationship between y and x square is Y = a - 2x square.
