Question

what are the coordinate points of b if b (-3, 15) is translated right 7 units, then down 8 units? (1 point) b = \square

Explanation:

Step1: Translate right 7 units (x - coordinate)

To translate a point \((x, y)\) right by \(a\) units, we add \(a\) to the \(x\) - coordinate. Here, the original \(x\) - coordinate of \(B\) is \(-3\) and \(a = 7\). So the new \(x\) - coordinate is \(-3+7 = 4\).

Step2: Translate down 8 units (y - coordinate)

To translate a point \((x, y)\) down by \(b\) units, we subtract \(b\) from the \(y\) - coordinate. The original \(y\) - coordinate of \(B\) is \(15\) and \(b = 8\). So the new \(y\) - coordinate is \(15 - 8=7\).

Answer:

\((4, 7)\)
