FAQs on Coordinate Geometry Video Lecture - Mathematics: Geometry - Grade 9

1. What is coordinate geometry?

Ans. Coordinate geometry is a branch of mathematics that deals with geometric figures using coordinates. It allows us to represent points, lines, and shapes on a graph by assigning numerical values to their positions.

2. How are coordinates represented in a Cartesian plane?

Ans. In a Cartesian plane, coordinates are represented as ordered pairs (x, y), where x represents the horizontal position (abscissa) and y represents the vertical position (ordinate) of a point.

3. How can we find the distance between two points in coordinate geometry?

Ans. The distance between two points (x1, y1) and (x2, y2) in coordinate geometry can be found using the distance formula: √((x2-x1)^2 + (y2-y1)^2).

4. What is the slope of a line in coordinate geometry?

Ans. The slope of a line in coordinate geometry is a measure of its steepness or incline. It is calculated as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line.

5. How can we determine if two lines are parallel in coordinate geometry?

Ans. Two lines are parallel in coordinate geometry if they have the same slope. If the slopes of two lines are equal, then they are parallel; otherwise, they intersect at a point.
