Example 10 Find the equation of the line, which makes intercepts โ€“3 and 2 on the x- and y-axes respectively. We know that ๐‘ฅ/๐‘Ž + ๐‘ฆ/๐‘ = 1 where a = x-intercept b = y-intercept Here, a = โ€“ 3 & b = 2 Putting values ๐‘ฅ/( โˆ’ 3) + ๐‘ฆ/2 = 1 (2๐‘ฅ + ( โˆ’ 3)๐‘ฆ)/( โˆ’ 3 ร— 2) = 1 (2๐‘ฅ โˆ’ 3๐‘ฆ)/( โˆ’ 6) = 1 2x โ€“ 3y = โ€“6 Hence, the required equation is 2x โ€“ 3y = -6
