1. Find the angle between the x -axis and the line joining the points (3,-1) and (4,-2)

2. Using slopes, find the value of x for which the points (x,-1), (2,1) and (4,5) are collinear.

3. Find the value of K so that the line 2x + ky -9 = 0may be parallel to 3x - 4y + 7 = 0

4. Find the value of K , given that the distance of the point (4,1) from the line 3x - 4y + K = 0 is 4 units.

5. Find the equation of the line through the intersection of 3x - 4y +1 = 0 5x + y -1 = 0which cuts off equal intercepts on the axes.

6. The slope of a line is double of the slope of another line. If tangent of the angle between them is 1/3 , find the slopes of the lines.

7. Point R(h, k )divides a line segment between the axes in the ratio 1:2. Find equation of the line.

8. The Fahrenheit temperature F and absolute temperature K satisfy a linear equation. Given that K=273 when F=32 and that K= 373 when F=212 Express K in terms of F and find the value of F when K=0

9. Assuming that straight lines work as the plane mirror for a point, find the image of the point (1,2) in the line x -3y + 4 = 0

10. A person standing at the junction (crossing) of two straight paths represented by the equations 2x -3y + 4 = 0and 3x + 4y -5 = 0wants to reach the path whose equation is 6x - 7y +8 = 0in the least time. Find equation of the path that he should follow.
