The x and y intercepts of a straight line are -4 and 5 respectively.
A point M on the straight line is equidistant from the x and y axes.
Determine the coordinates of the point M
~~~~~~~~~~~~~~~~~~~

The x-intercept is the point (-4,0).


The y-intercept is the point (0,5).


The slope of the line is  m = %285-0%29%2F%280-%28-4%29%29 = 5%2F4.


An equation of the line is  y-5 = %285%2F4%29%2A%28x-0%29,  or  y - 5 = %285%2F4%29x.



If the point M in this line is equidistant from the x- and y- axes,

then we should place x = y in the last equation.


It gives  x - 5 = %285%2F4%29x,  or  4x - 20 = 5x,  -20 = 5x - 4x,  x = -20.


Thus the coordinates of the point M are  (x,y) = (-20,-20).    ANSWER

Solved.
