Detailed explanation-1: -There are in all 7 exercises in class 10 mathematics chapter 3 (Pair of linear equations in two variables).
Detailed explanation-2: -A pair of numbers locate points on a plane called the coordinates. The distance of a point from the y-axis is known as abscissa or x-coordinate. The distance of a point from the x-axis is called ordinates or y-coordinate. Example: Consider a point P(3, 2), where 3 is the abscissa and 2 is the ordinate.
Detailed explanation-3: -Coordinate Geometry: The branch of Mathematics in which algebraic methods are used to solve geometrical problems is known as coordinate geometry. As shown in the figure, the line XOX′ is known as the X-axis and YOY′ is known as Y-axis. The point O is called the origin.
Detailed explanation-4: -Equation of a Straight Line. Distance Formula. Distance from the Origin. Section Formula. Midpoint Formula. Area of a Triangle. Area of a Polygon. The Centroid of a Triangle.
