Figure B: a reflection across the y-axisFigure a 180° rotation around the origin

strojnjashka [21]

Since I can't see the figure on the coordinate plane, I can't give you exact coordinates for you to plot to get Figure B or Figure C. But I can tell you the transformation rules for reflection across the y-axis and the 180 rotation around the origin.

Rule for reflection across y-axis
(x, y) $\rightarrow$ (-x, y)
For example: Point B in a sample figure has the coordinate point of (1,2) would have a point of (-1, 2) when reflected across the y-axis.

Rule for rotating 180 degrees
(x, y) $\rightarrow$ (-x, -y)
For example: Point C in a sample figure has the coordinate point of (3, 4) would have a point of (-3, -4) when rotating 180 degrees around the origin.

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.
