Let's plot the points (1,1), (3,7) (9,1) and (12,1) on a graph sheet and verify whether they lie on a line.

Let’s put the points (1,1),(2,2) and (3,3) on the graph paper and see whether they are collinear.

Let's plot the points A (4,0), B(0,6), C (2,5), D(7,1) E (?, 5) and F(?,5) on a graph sheet.

Plot the points (0,0), (0,3), (4,3), (4,0) in graph sheet. Join the points with straight lines to make a rectangle. Find the area of the rectangle.

Prove that the points (3,1), (5,-5) and (-1,13) are collinear . Find the equation of the straight line on which the points lie.

For what value(S)of K the point (1,-1),(2,1) and (K,5) lie on the same line?

Verify whether the points (1, 5), (2, 3) and (-2, -1) are collinear or not.

What can you say about the position of the points (1,2), (1,3), (1,-4), (1,0) and (1,8). Locate on a graph sheet.

Show that the staright line joining the points (-1, 0, -2) and (1, 3, -1) is perpendicular to the straight line joining the points (9, 1, -6) and (7, 2, -5)

Prove that the straight line joining the points A(4, -3, 2) and B(2, -1, -1) is parallel to the straight line joining the point C(7, -3, 5) and D(1, 3, -4).

Let’s write 4 collinear points on a graph sheet and write the coordinates of the points. Similarly, plotting the points on the graph sheet and joining them we get some pictures. What will we call that?
