DERIVATIONS OF FORMULAS TO FIND EQUATION OF STRAIGHT LINES
|NCERT EXERCISE 10.2|
Question 7. Passing through the points (–1, 1) and (2, – 4).
Slope intercept form and meaning of intercept
Question 5. (using Slope intercept form) Intersecting the x-axis at a distance of 3 units to the left of origin with slope –2.
Question 6. (using Slope intercept form) Intersecting the y-axis at a distance of 2 units above the origin and making an angle of 30 with positive direction of the x-axis.
Normal Form of Straight Line
Question 8. (using Normal Form) Perpendicular distance from the origin is 5 units and the angle made by the perpendicular with the positive x-axis is 30.
