## SPM Math P1 Q8

- Variables x and y are related by the equation 4 y=2(x-1)^{2}+3 k where k is a constant.
(a) When y is plotted against (x-1)^{2}, a straight line is obtained, which intersects the y -axis at (0,-6). Find the value of k.

(b) Hence, find the gradient and the y intercept for the straight line obtained by

plotting the graph of (y+x) against x^{2}
