The graph of:
(-3,-6)
(7,-6)
Plotting the above graph we find a horizontal line at:

y = -6

The y-intercept is -6

The equation of a horizontal line is

y = b

where b is the y-intercept.

Since the slope of a horizontal line is 0 (zero), the general formula for the standard form equation,

y = mx + b

becomes

y = 0x + b

Therefore:

y = b

Since the line is horizontal, every point on that line has the exact same y value. This y-value is therefore also the

y-intercept.
