Answer:
The correct choices are; B,C,E, and F.
Step-by-step explanation:
The given equation is;
We solve for m to obtain:
We also solve the remaining equations to see which ones give the same result.
A:
B:
C:
D:
E:
F:
The equivalent equations are; B,C,E, and F.
See the attached figure. The original triangle is shown in red (triangle ABC). The line of reflection is the blue dashed line. This is the equation y = x. Reflecting triangle ABC over the line y = x results in the purple triangle A'B'C'.
Note how the x and y values swap places.
We have...
point A = (5,1) turn into point A' = (1,5)
point B = (8,1) turn into point B' = (1,8)
point C = (8,6) turn into point B' = (6,8)
The swap occurs because the rule (x,y) --> (y,x) tells this to happen.
The purple triangle is the final answer.
