Lecture - 11 Chapter 10 Straight Lines

You will need to understand how to make equations and read information from equations before continuing
Question 7. Find equation of the line parallel to the line 3x–4y+2=0 and passing through the point (–2,3). Question 8. Find equation of the line perpendicular to the line x – 7y + 5 = 0 and having x intercept 3.

Question 9. Find angles between the lines \sqrt{3}x+y=1 and x+\sqrt{3}y=1

Question 10. The line through the points (h, 3) and (4, 1) intersects the line 7x- 9y-19=0 at right angle. Find the value of h.

Question 12. Two lines passing through the point (2, 3) intersects each other at an angle of 60 If slope of one line is 2, find equation of the other line.

Question 13. Find the equation of the right bisector of the line segment joining the points (3, 4) and (–1, 2).
