Straight Line Equation from Intercepts
Find the equation of the straight line which intercepts from the positive parts of the coordinate axes (X-axis and Y-axis) two parts of lengths 4 and 9 units respectively.
(a) \( \frac{x}{4} + \frac{y}{9} = 1 \)
(b) \( 9x + 4y = 36 \)
(c) Both a and b
(d) \( \frac{x}{9} + \frac{y}{4} = 1 \)
Correct Answer: (c) Both a and b

Explanation:
Using intercept form \( \frac{x}{a} + \frac{y}{b} = 1 \):
- x-intercept (a) = 4
- y-intercept (b) = 9
Therefore:
\( \frac{x}{4} + \frac{y}{9} = 1 \) (option a)
Which can be converted to \( 9x + 4y = 36 \) (option b)
