Answers:
1. d
2. c
3. a
4. b
==================================================
Explanations:
The general slope intercept form is y = mx+b
m = slope
b = y intercept
So if we're told that the slope is m = -4 and the y intercept is b = 2, then y = mx+b turns into y = -4x+2. Saying "the y intercept is b = 2" is the same as saying "the y intercept is (0,2)". So that explains why 1 matches with d.
2 matches with c because y = 2 is the same as y = 0x+2. Often the equation is simplified as much as possible. It may not be obvious after simplifying how to go from y = 2 to y = 0x+2
3 matches with 'a' for similar reasons as above. In this case m = 2 and b = -4 leads to y = 2x+(-4) which becomes y = 2x-4
4 matches with b for similar reasons as above.
