Slope of the line x/a + y/b = 1 isA) 1/bB) 1/aC) a/bD) - b/a

Answer»

Correct option is (D) -b/a

Given line is \(\frac{x}{a}+\frac{y}{b} = 1\)

\(\Rightarrow\) \(\frac{y}{b}=1-\frac{x}{a}\)

\(\Rightarrow y=-\frac bax+b\)

By comparing with \(y=mx+c,\) we get \(m=-\frac{b}{a}\)

\(\therefore\) Slope of the line \(\frac{x}{a}+\frac{y}{b} = 1\) is \(m=-\frac{b}{a}.\)

Correct option is D) - b/a
