Answer: y = 2x + 4
Explanation:
The slope is rise over run, so if we take the 2 points (0, 4) and (-2, 0), we can see that the line moved up 4 and to the right 2. That means the slope is 4/2, which is 2.
So now we know that the equation is y = 2x + ?, and by using a simple point we can find out that the ? is 4.
So, the equation is y = 2x + 4
