उत्तर
Ordinate of all points on the x-axis is 0.
Explanation:
Ordinate of all points on the x-axis is zero. Because ordinate (or y-coordinate) of a point is perpendicular distance of this point from the x-axis measured along the y-axis.
If point lies on x-axis, then the perpendicular distance of point from x-axis will be zero, so ordinate will be zero.

If the points P(1, 2), Q(0, 0) and R(x, y) are collinear, then find the relation between x and y.
Given points are P(1, 2), Q(0, 0) and R(x, y).
The given points are collinear, so the area of the triangle formed by them is `square`.
∴ `1/2 |x_1(y_2 - y_3) + x_2(y_3 - y_1) + x_3(y_1 - y_2)| = square`
`1/2 |1(square) + 0(square) + x(square)| = square`
`square + square + square` = 0
`square + square` = 0
`square = square`
Hence, the relation between x and y is `square`.
The distance of the point (–4, 3) from y-axis is ______.
