FAQs on Co-ordinate geometry Practice Questions - 2 Video Lecture - Crash Course for UGC NET Economics

1. What is the equation of a line passing through two given points in co-ordinate geometry?
Ans. To find the equation of a line passing through two given points (x1,y1) and (x2,y2), we can use the point-slope formula: y - y1 = ((y2-y1)/(x2-x1))(x - x1).
2. How do you determine if two lines are parallel in co-ordinate geometry?
Ans. Two lines are parallel if their slopes are equal. If the slopes of two lines are m1 and m2, and m1 = m2, then the lines are parallel.
3. What is the distance formula in co-ordinate geometry?
Ans. The distance formula in co-ordinate geometry is given by d = sqrt((x2-x1)^2 + (y2-y1)^2), where (x1,y1) and (x2,y2) are the coordinates of two points.
4. How do you find the slope of a line in co-ordinate geometry?
Ans. The slope of a line can be found using the formula m = (y2-y1)/(x2-x1), where (x1,y1) and (x2,y2) are any two points on the line.
5. How can you determine the equation of a circle in co-ordinate geometry?
Ans. The equation of a circle with center (h,k) and radius r is given by (x-h)^2 + (y-k)^2 = r^2.
