Question

the equation of the line making intercepts of equal magnitude and opposite signs , and passing through the point (-3,-5) is __________.​

Answer 1

$\frac{x}{a} - \frac{y}{a} = 1 \\ it \:passes \: through \: ( - 3 \: - 5) \\ so \: \frac{ - 3}{a} - \frac{( - 5)}{a } = 1 \\ a = 2 \\ so \: equation \: of \: line = x - y = 2$
