4. The coordinates for the vertices of ∆ABC are A (2, 3), B (4, –3), and C (–5, –1). ∆ABC is reflected across the line y = x to create ∆A'B'C' and then reflected across the y-axis to create ∆A'’B’'C'’.

Part A:
Find the coordinates of the vertices of ∆A'B'C'. (1 pt)

Part B:
Find the coordinates of the vertices of ∆A’'B’'C’'. (1 pt)

do you know this one?

phi · Answer

reflected across the line y = x 
I think if you swap the (x,y) coords, that has this effect.

phi · Answer

then
 reflected across the y-axis to create ∆A'’B’'C'’.
here,  if you multiply the x by -1, and keep the same y, this will reflect the point about the y-axis
