Answer:
Note:--So you didn't put a slope in but I'll just use -m for this instead then later you can input it yourself since you just put a negative sign instead of a number-- Now here is the Answer:
y=-mx-3
Once you input the number put a "x" next to it.
The formula is y=mx+b and the slope is m and the y intercept is b. So since you already have the numbers just input them into the formula! Easy peasy!
