The y-intercept is whatever number (with no variable) is added onto the end of the equation y=mx+b. In this case b is the y-intercept.
In y=15x the y-intercept is 0 because there is no number without a variable on the end.

y = mx + b y = 0.666666666666666666667(x) + 6 m = slope b = y intercept
It is in slope intercept form. The slope is 0 and the y-intercept is -2.
The y intercept is when x =0, so the answer is -6
2x plus y = -3 (subtract 2x from both sides) y = -2x - 3 slope = -2 y-intercept = -3
-3
