Answer:
B. y = -3x + 2
Step-by-step explanation:
The equation for slope intercept form is 
We need to find the slope and y-intercept.
<u>Let's find the slope first.</u>
Using the slope formula:

So, the slope of the points (0,2) and (2,-4) is -3.
-3 will replace m.
The Y-intercept, or b, is 2, since (0,2) is on the y-axis.
We end up with: 
<em>Option B is correct since it matches our equation. </em>
