Question -
Answer -
Given:
A line passingthrough (1, -2)
Let us assume, theequation of the line cutting equal intercepts at coordinates of length ‘a’ is
By using the formula,
The equation of theline is x/a + y/b = 1
x/a + y/a = 1
x + y = a
The line x + y = apasses through (1, -2)
Hence, the pointsatisfies the equation.
1 -2 = a
a = -1
∴ The equation of theline is x+ y = -1
