When the graph of the given function is flipped over the line , the coordinates will swap.
The mapping for a reflection in the line is .
We can observe that one portion of the graph is in the first quadrant . When we flip this part we will get , which is still in the first quadrant.
Also, when we flip the portion of the graph in the second quadrant (-x,y), we will obtain (y,-x), which is standing for all coordinates in the fourth quadrant.
The image is shown in the attachment.
x = -3
y = -18
to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.
x-1/3(3x-9) = -3 since y=3x-9 substittute y.
x + x +3 = -3
substitute again into y=3x-9
what is the question? i am guessing you are looking for the area.
to find an area, you have to do length x width.
in this case, it would be 12 ft x 4 ft = 48 sq. ft
