The equation of straight line passing through point m (3,4) with equal intercept on the coordinate axis is______ .

The equation of straight line passing through point m (3,4) with equal intercept on the coordinate axis is______ .

When the line passes through the origin, the linear equation is y = 43x, that is, 4x-3y = 0; when the line does not pass through the origin, let the linear equation be x + y = A. then 3 + 4 = a, a = 7. The linear equation is x + Y-7 = 0. The linear equation passing through the point m (3, 4) with equal intercept on the coordinate axis is 4x-3y = 0 or x + Y-7 = 0. So the answer is: 4x-3y = 0 or x + Y-7 = 0
