Find the image of (–1, 2) reflected across the y-axis.
a: (1, 2)
b: (-1, 2)
c: (1, -2)
d: (-1, -2)

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
