If ABC is reflected across the yaxis, what are the coordinates of A? ... what are the coordinates for A'B'C' after ABC has been reflected across the x-axis ? ... 1) if ABC is reflected across the y axis what are the resulting coordinates for points A,B, and C.
A reflection across the y-axis means the point is equal but opposite distance from the y-axis. It begins at 4 units to the LEFT (negative) of the y-axis, so after the reflection, it should be 4 units the the RIGHT (positive) of the y-axis. This has no change on the y-value of the point, because no matter the y-value, the point will still be the same distance from the y-axis. Long story short, if you're reflecting across the y-axis, change the sign of the x-coordinate. If you're reflecting across the x- axis, change the sign of the y-coordinate. That's why the answer is (4, -6).
"The product" is the term used to describe the answer of a multiplication equation. "increased by" means you're adding. "a number" refers to a variable.
