A line contains the points (2,5) and (4,7). Translate this line up 4 units and to the left 4 units. What are the points after the translation?

Answer 1

To translate a point up by a certain amount, we add that amount to the y-coordinate. To translate a point to the left by a certain amount, we subtract that amount from the x-coordinate.

The translation up 4 units would change the y-coordinate of each point from (2,5) to (2, 5+4) = (2, 9) and from (4,7) to (4, 7+4) = (4,11).

The translation to the left 4 units would change the x-coordinate of each point from (2,9) to (2-4, 9) = (-2,9) and from (4,11) to (4-4,11) = (0,11).

Therefore, the points after the translation are (-2,9) and (0,11).
