Worked practice questions

If a point is reflected in the x-axis, the new co-ordinates of (a, b) become

(-a, b)
(a, -b)
(-a, -b)
(b, a)

Show answer and solution

Correct answer: B. (a, -b)

1. Reflection in x-axis flips the sign of the y-coordinate. 2. x stays the same. 3. So (a, b) becomes (a, -b). 4. Hence option A is correct. _Source: Selina Concise Mathematics Class 9, Ch 26 Co-ordinate Geometry (Mistral OCR'd PDF), section on reflection_

The distance of point (5, 0) from the origin is

10 units
5 units
0 units
25 units

Show answer and solution

Correct answer: B. 5 units

1. Use d = sqrt(x^2 + y^2). 2. = sqrt(5^2 + 0^2) = sqrt(25). 3. = 5 units. 4. So the distance is 5 units. _Source: Selina Concise Mathematics Class 9, Ch 26 Co-ordinate Geometry (Mistral OCR'd PDF), section on distance from origin_
