Answer:
y = -1/2x + 2
Step-by-step explanation:
If you are talking about a linear equation then b=2
The slope is y2 - y1 / x2 - x1 so 2-0/0-4 = 2/-4 = -1/2
So put it all together in y = mx + b so y = -1/2x + 2

Answer:
Infinite solutions.
Step-by-step explanation:
A ratio, which is essentially a fraction, can be written in an infinite number of ways and still have the same value..
As an example:
2/1 = 2
6/3 = 2
As long as both the top and bottom of a fraction are multiplied by the same value, the fraction will keep the same value.
So, any ratio that's a multiple of 1/5 is equivalent.
