Any line and be expressed (though not uniquely):

where both are non-zero.

You are told that the x and y intercepts are the same.

When we have,

.

Thus,

(divison by zero did not occur based on the wording of the problem).

----> y-intercept.

When we have,

.

Thus,

(divison by zero did not occur based on the wording of the problem).

----> x-intercept.

They are equal.

Thus,

.

Hence,

Divide by ,

,

Thus,

Thus,
