# Find Equation of the Line Passing Through the Point (2, 2) and Cutting off Intercepts on the Axes Whose Sum is 9. - Mathematics

Find equation of the line passing through the point (2, 2) and cutting off intercepts on the axes whose sum is 9.

#### Solution

The equation of a line in the intercept form is x/a + y/b = 1 ... (i)

Here, a and b are the intercepts on x and y axes respectively.

It is given thata + b = 9 ⇒ b = 9 – a … (ii)

From equations (i) and (ii), we obtain

If a = 6 and b = 9 – 6 = 3, then the equation of the line is

x/6 + y/3 = 1 => x +2y - 6 = 0

If a = 3 and b = 9 – 3 = 6, then the equation of the line is

x/3 + y/3 = 1 => 2x + y - 6 = 0
