Answer:

The correct answer is NO.

Step-by-step explanation:

John is graphing two lines with equations say ax + by + c = 0 and dx + ey +f =0 on his graphing calculator.

For John to get a unique solution the coefficients should follow the following condition $\frac{a}{d} \neq \frac{b}{e}$ . So when he plots the lines he get an intersecting pair of lines.

For John to get no solution the coefficients should follow the following condition $\frac{a}{d} = \frac{b}{e} \neq \frac{c}{f}$ . When we plot in this case we get two parallel lines.

For John to get an infinite many solution the coefficients should follow the following condition $\frac{a}{d} = \frac{b}{e} = \frac{c}{f}$ . And when we plot the lines in this case we get one line superimposed on the other.
