HHHHHEEEEEELLLLLLLPPPPPPPP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Find the y intercepts of these please:

1. The slope is: 6/2...3/1...3
2. The slope is: 10/2...
3. The slope is: 2/2...2
4. The slope is: 2/2...2

The formula for a slope intercept is:

y = mx + b, where m is the value of the slope.

If b = 0, the y intercept will always be 0.

By the way, 10/2 = 5 and 2/2 = 1

I hope this helps. Thanks for asking.
