Question

A straight line makes on the coordinate axes positive intercepts whose sum is 7

Answer 1

Step-by-step explanation:

X / a + y / b = 1 where a + b = 7.

$\frac{x}{3} + \frac{y}{4} = 1 \\ \\ or \\ \\ \frac{x}{4} + \frac{y}{3} = 1 \\ \\ or \\ \\ \frac{x}{5} + \frac{y}{2} = 1 \\ \\ \\ or \\ \\ \\ \frac{x}{2} + \frac{y}{5} = 1 \\ \\ or \\ \\ \\ \frac{x}{1} + \frac{y}{6} = 1 \\ \\ or \: \: \\ \\ \frac{x}{6} + \frac{y}{1} = 1$
