On a coordinate plane, how are the locations of the points (-4, -9) and (4, -9) related?

(x, y)

(-4, -9) → x = -4 and y = -9

(4, -9) → x = 4 and y = -9

The reflection of the point (-4, -9) across the y-axis is the point (4, -9).

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
