What must be true of the coordinates of a point on a graph?
A
For C=12x+600C=12x+600C=12x+600 and R=30xR=30xR=30x, break-even occurs algebraically at x=1003\boxed{x=\frac{100}{3}}x=3100, where the common value is 100010001000.
B
They must satisfy the graph's equation.
C
The line y=2x+ky=2x+ky=2x+k touches y=x2y=x^2y=x2 when k=−1k=-1k=−1, at the point (1,1)\boxed{(1,1)}(1,1).
D
The number of items must be a whole number.
