Question

1.The vertices of a triangle are P(–7, –4), Q(–7, –8), and R(3, –3). Name the vertices of the image reflected across the line y = x.

P'(4, 7), Q'(8, 7), R'(3, –3)
P'(4, –7), Q'(8, –7), R'(3, 3)
P'(–4, –7), Q'(–8, –7), R'(–3, 3)
P'(–4, 7), Q'(–8, 7), R'(–3, –3)

2.The vertices of a triangle are A(–6, –4), B(–3, 5), and C(1, –1). Name the vertices of the image reflected across the x-axis.

A'(–6, 4), B'(–3, –5), C'(1, 1)
A'(–6, –4), B'(–3, 5), C'(1, –1)
A'(6, –4), B'(3, 5), C'(–1, –1)
A'(6, 4), B'(3, –5), C'(–1, 1)

Answer 1

the line y=x swaps xs and ys around. (x,y) -> (y,x)

Answer 2

to reflect in the x axis is to simply fall to the other side of the x axis, y -> -y

Answer 3

do you have the answers to these like all of them ? i really need them
