The point whose ordinate is -3 and which lies on y-axis is

• (-3,0)

• (0,-3)

• (1,-3)

• -2

• -5

• 1

• -1

Abscissa of all points on the y-axis is

• I Quadrant

• II Quadrant

• III Quadrant

• IV Quadrant

Anu's school is 5 km to the west and 3 km north of his house. He represented his house and his school on a coordinate grid, with his house located at the origin, and the positive x axis represent the direction that is east of his house. If 1 unit on the coordinated grid represents 1 km, what will be the coordinate of his school?

• (5,3)

• (-5,3)

• (3,5)

• (-3,5)

If y-coordinate of a point is zero, then where will this point lie in the coordinate plane?

Answer explanation

On the x-axis

Write the coordinate of a point on x-axis at a distance of 6 units from the origin in the positive direction of x-axis and then justify your answer

Answer explanation

As, any point on x-axis has coordinate (x,0), where x is the distance from origin, so required coordinates are (6,0).

The points in which abscissa and ordinate have different signs will lie in which quadrant(s)?

Answer explanation

II & IV quadrants
