a.what's r?!
b.it turns from 3, 1 to 3, -1 and 1, 3 to 1, -3 and 5, 4 to 5, -4

Answer:

(-1,3) (-3,1) and (-4,5)

Step-by-step explanation:

Given is a triangle ABC with coordinates (1,3)(3,1) (4,5)

First transformation is reflection over yaxis i.e. x=0

Reflection in the y -axis: A reflection of a point over the y -axis is shown. The rule for a reflection over the y -axis is (x,y)→(−x,y)

Hence x coordinate will change sign

The resulting coordinates would be

(-1,3) (-3,1) and (-4,5) respectively

y coordinates will remain the same because of this reflection.

Hence new coordinates would be

(-1,3) (-3,1) and (-4,5)  For A, B and C in the same order
