Plot any three points such that x-coordinate of each point is equal to its y-coordinate. Join these points in pair. Do they lie on a line passing through the origin?

Plotting any three points such that x-coordinate of each point is equal to double of its y-coordinate and Joining these points in pairs, we get points lie on A passing through B .

Plot the points (2,8),(7,8) and (12,8). Join these points in pairs. Do they lie on a line? what do you observe?

Find the coordinates of the points on the curve y=x^2+3x+4 , the tangents at which pass through the origin.

Find the coordinates of the points on the curve y=x^(2)+3x+4, the tangents at which pass through the origin.

Decide which of the following statements is true and which is false. Give reasons for your answer. A point whose x-coordinate is zero, will lie on the y-axis. A point whose y-coordinate is zero, will lie on x-axis. The coordinates of the origin are (0, 0). Points whose x a n d y coordinates are equal, lie on a line passing through the origin.

The coordinates of the point P are (-3,2) . Find the coordinates of the point Q which lies on the line joining P and origin such that OP=OQ.

If both the coordinates of a point are negative then that point will lie in
