Practice the questions given in the worksheet on pointslope form of the straight line.
If the slope = m and the line passes through the point (x\(_{1}\), y\(_{1}\)), the equation of the lien is y  y\(_{1}\) = m(x  x\(_{1}\)), which is known as pointslope form of a straight line.
1. Determine the equation of the straight line whose inclination is 60° and which passes through the point (3, 4).
2. Find the equation of the straight line whose slope is 3 and passes through the point (1, 2)
3. Find the equation of the straight line whose slope is 2 and passes through the point (3, 0)
4. Find the equation of the straight line whose inclination is 45° and passes through the point (4, 1)
5. A straight line passes through the point ( 1, 4) and makes an angle 60° with the positive direction of the xaxis. Find the equation of the straight line.
6. Find the equation of the straight line whose inclination is 60°
and passes through the origin.
7. Find the equation of the line which is inclined at 135° with the negative direction of the xaxis and passes through the point (1, 2)
8. Find the equation of the line which is inclined at 45° with the positive direction of the yaxis and passes through the point (3, 2)
9. Find the equation of the straight line parallel to the yaxis and passes through the point (1, 3).
10. Find the equation of the straight line parallel to the yaxis and passes through the point (2, 3).
11. Find the equation, of the straight line whose inclination is 600 and which passes through the midpoint of the linesegment joining the points (3,  4) and (7, 8).
