Hi Adharsh:

y = 0

y = 5

These are both horizontal lines, parallel to each

other. As such there is no crossing point,

or point in common, thus the system has no

solution.

*******************************

Put the lines in slope intercept format:

y = mx + b, m=slope, b = y-intercept.

If the slope is the same they are parallel.

If they are parallel and the y-inercept

is different, the lines never cross.

y = 0

y = 0x + 0

m = 0, b = 0

y = 5

y = 0x + 5

m = 0, b = 5

Same slope, different y-intercept. No solutions.

The same is immediately true of a vertical line

of form x = n where n is some number.

This is a vertical line, straight up and down.

If we have two lines, x = a, x = b and

a and b are different the lines never cross.

Understand?
