A straight line makes intercepts of -3 and 2 on the x and y axes respectively. Find the equation of the line.
2x + 3y + 6 = 0
3x - 2y - 6 = 0
-3x 2y - 6 = 0
-2x + 3y - 6 = 0
Explanation
Recall:
| x
a |
+ | y
b |
=1 |
Where 'a' and 'b' are the x and y intercept respectively.
| x
-3 |
+ | y
2 |
=1 |
2x-3y = -6
2x - 3y + 6 = 0 -------(1)
multiply through by -1
-2x + 3y - 6 = 0
