The vertices of a triangle are a(7.5), b(4,2), and c19. 2). what is

Find y to the nearest hundreds place

Right ∆abc has coordinates a(-7, 3), b( -7, 10), and c(-1, 3). the triangle is reflected over the x - axis and then reflected again over the y - axis to create ∆a'b'c'. which are the coordinates of vertex a'?
