Question

click twice to draw a line. click a segment to erase it.

Explanation:

Step1: Identify Coordinates

First, determine the coordinates of the two points. The first point (let's say Point A) is on the y - axis. From the graph, it seems to be at (0, 9) (since it's on the y - axis, x = 0 and y = 9). The second point (Point B) has an x - coordinate of 8 and a y - coordinate of 9? Wait, no, looking at the purple cursor, maybe the second point is (8, 9)? Wait, no, maybe I misread. Wait, the first point is at (0, 9) (the yellow dot on the y - axis) and the second point is at (8, 9) (the yellow dot near the purple cursor).

Step2: Draw the Line

To draw a horizontal line (since both points have the same y - coordinate, y = 9), we connect the two points (0, 9) and (8, 9). We can do this by clicking on (0, 9) and then on (8, 9) as per the instruction "Click twice to draw a line".

(Note: Since this is a graph - drawing task, the main steps are identifying the points and then drawing the line between them. If we were to represent the line equation, it would be y = 9, a horizontal line parallel to the x - axis with y - intercept 9 and slope 0.)

Answer:

Draw a line between the point (0, 9) (on the y - axis) and the point (8, 9) (near the purple cursor) by clicking on each point once. The line will be horizontal (y = 9) connecting x = 0 to x = 8 at y = 9.
