The equation of the line would be y = (1/2)x.
To find the equation of a line that is reflected through the line y = x, we just switch the x and y. Then, solve for y.
y = 2x
x = 2y
0.5x = y
I think it is 4,4 because when i graphed it turned out like that al 7 are
-2,2
-1,1
0,0
1,1
2,2
3,3
4,4
this is what i got i might be wrong because it might not be what you meant but i interpreted this way so i did it this way
Hello.
JK (or any other combination of letters) doesn't stand for anything in geometry. The purpose of these letters is to reference certain angles and sides of a figure without having to describe the angles/sides in relation to other angles/sides to know exactly which angle or side is being referenced.
Hope this helps!
