Question

reflect triangle abc over the vertical line x = 3. what are the coordinates of vertex a? (1 point)

Explanation:

Step1: Find distance from point A to line x = 3

The x - coordinate of point A is 0. The distance from x = 0 to x = 3 is $d=|3 - 0|=3$.

Step2: Calculate new x - coordinate of A'

Since we are reflecting over x = 3, we move the same distance on the other side of the line. The new x - coordinate is $3+(3 - 0)=6$.

Step3: Determine y - coordinate of A'

The y - coordinate remains the same during a reflection over a vertical line. The y - coordinate of A is 9, so the y - coordinate of A' is also 9.

Answer:

$(6,9)$
