Question

Plot the points A( 1,-1) , B(4,5) A) draw a line segment joining these points B) write the coordinate of a point on this line segment between the points C) extend this line segment and write the coordinate of the points on this line which lies outside the line segment

Answer 1

in point A(1, -1), x-coordinate is positive and y-coordinate is negative, so it lies in IV quadrant. In point B(4, 5), both coordinates are positive, so it lies in I quadrant. On plotting these point, we get the following graph.

Answer 2

Answer:

A) For plotting (1, -1) in the coordinate plan,

Go right side 1 unit from origin in the positive x -axis then go 1 unit downward,

Similarly, for (4, 5),

Go right side 4 units from origin in the positive x -axis then go 5 units upward,

Then join the points,

We get the line segment.

B) By the graph we found that,

Line segment AB passes through the point (2.5, 2),

Thus, (2.5, 2) is between the points A and B,

C) By extending this line segment we found that points (-3, 0) and (5, 7) lie outside the line segment.
