For what values of k will the pair of equations kx + 3y = k-3 , 12x + ky = k have no solution

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

x = 12

y = 1

for the points!
