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.

In attempting to solve the system of equations and , John graphed the two equations on his graphing calculator. Because he saw o
asambeis [7]

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.

Since after graphing, John sees only one line, the lines must have superimposed on one another giving John an infinite number of solutions.
