Answer:
Your equation is y = mx + b
y is your output, x is your input, m is your slope, and b is the y intercept (0,b).
So if you know the slope is -2, you know the m value.
If you know the y intercept is (0,3) you also know the b value.
Your overall equation would be y = -2x + 3
You want x and y to remain in there to keep this a function/equation.
