Question

if x/a+y/a = 1 passes through the points (2, -3) and (4,-5) then find the value of (a, b)​

Answer 1

Answer:

$a = -1 \: \: \: \: \: \: \: \: \: \: \: b = -1$

Step-by-step explanation:

$\frac{x}{a} + \frac{y}{b} = 1 \\ \\ \frac{2}{a} + \frac{-3}{b} = 1 \\ \\ \frac{4}{a} + \frac{ - 5}{b} = 1 \\ \\ \\ \\ solving \: these \: \: \: \\ \\ \frac{-6}{b} + \frac{5}{b} = 2 - 1 \\ \\ \frac{-1}{a} = 1 \\ \\ a = -1 \\ \\ \\ \frac{-2}{1} + \frac{-3}{b} = 1 \\ \\ \\ \frac{-3}{b} = 1 +2 \\ \\ \frac{-3}{b} = 3 \\ \\ b = - 1 \\ \\ \\ \\ \\ a = -1 \: \: \: \: \: \: \: \: \: \: \: b = -1$
