NARRATOR: Question one. Part a. Find the distance between the points A (6, 3) and B (-4, 3). Part b. Find the distance between the points A (6, 3) and B (6, -4).

[On a graph, the horizontal x axis is marked from -6 to 6. The vertical y axis is marked from -2 to 6. A horizontal red line runs through y = 3 from point A (6, 3) to point B (-4, 3).]

NARRATOR: Part a. The line segment AB is parallel to the x axis. The distance between A and B is given by 6 minus negative four, which is equal to 10.
