Question

If the coordinates of the two points are P (–7, 5) and Q (–6, 9), then (abscissa of P) + (abscissa of Q) is ​

Answer 1

Answer: (Abscissa of P) + (Abscissa of Q) = - 13.

Explanation:

We know,

• Abscissa of a point = Distance of the point from Y-axis = Value of X coordinate &
• Ordinate of a point = Distance of the point from X-axis = Value of Y coordinate.

Therefore,

(Abscissa of P) + (Abscissa of Q)

= (- 7) + (- 6)

= - 7 - 6

= - 13.

There are 4 conic sections:

• Parabola
• Hyperbola
• Eclipse
• Circle

& parts of a parabola:

• Vertex: Point from with the parabola takes a 'U-turn'.
• Axis of Symmetry: Line which divides the parabola into 2 halves.
• Focus: Point from which the line joining any two corresponding points are equal in distance.
• Directrix: ⊥ to focus.
