Find the equations of the straight lines which cut off an intercept 5 from the y – axis and are equally inclined to the axes.

A line which cut off an intercept 5 from the y – axis are equally to axes.

To Find: Find the equation


The formula used: The equation of the line is y = mx + c


Explanation: If a line is equally inclined to the axis, then


Angle θ = 45o and θ = (180 – 45) = 135o


Then, The slope of the line, m = tan θ


m = 1


Since, the intercept is 5, C = 5


Now, The equation of the line is y = mx + c


y = 1x + 5


y – x = 5


Hence, The equation of the line is y – x = 5.
