## FAQs on RD Sharma MCQs: Coordinate Geometry - Mathematics (Maths) Class 9

 1. What is the coordinate geometry? Ans. Coordinate geometry is a branch of mathematics that deals with the study of geometric figures using the principles of algebra. It involves representing points, lines, and curves on a coordinate plane using coordinates and equations.
 2. How do you find the distance between two points in coordinate geometry? Ans. To find the distance between two points in coordinate geometry, you can use the distance formula. The distance between two points (x1, y1) and (x2, y2) is given by the formula: Distance = √((x2 - x1)^2 + (y2 - y1)^2)
 3. What is the equation of a straight line in coordinate geometry? Ans. The equation of a straight line in coordinate geometry can be represented in various forms, including slope-intercept form (y = mx + c), point-slope form (y - y1 = m(x - x1)), and general form (Ax + By + C = 0), where m is the slope of the line and (x1, y1) is a point on the line.
 4. How can you determine if two lines are parallel using coordinate geometry? Ans. Two lines are parallel if and only if their slopes are equal. In coordinate geometry, you can determine if two lines are parallel by comparing their slopes. If the slopes of two lines are equal, then the lines are parallel; otherwise, they are not.
 5. What is the midpoint formula in coordinate geometry? Ans. The midpoint formula in coordinate geometry is used to find the coordinates of the midpoint of a line segment. The coordinates of the midpoint between two points (x1, y1) and (x2, y2) are given by the formula: Midpoint = ((x1 + x2)/2, (y1 + y2)/2)
