The correct option is, (B) (2, –23).
What is called co-ordinate?
- Coordinates are distances or angles, represented by numbers, that uniquely identify points on surfaces of two dimensions (2D) or in space of three dimensions ( 3D ).
- There are several coordinate schemes commonly used by mathematicians, scientists, and engineers.
What is co-ordinate with example?
- A set of values that show an exact position.
- On graphs it is usually a pair of numbers: the first number shows the distance along, and the second number shows the distance up or down.
- Example: the point (12,5) is 12 units along, and 5 units up.
What is the co ordinate formula?
- One of the important formula of coordinate geometry is the equation of the straight line which is y = mx + c.
- Here m is the slope and c is the y-intercept (tan θ = m, here θ is the angle that the line makes with the positive x-axis).
What is coordinate of a point?
- The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane.
- Recall that the coordinate plane has two axes at right angles to each other, called the x and y axis.
- The coordinates of a given point represent how far along each axis the point is located.
