Answer:
so i can give you the answer to number 4 so you can do the rest.
Explanation:
so slope is -3, and the y-intercept is 7
y = mx+b is the formula used and if m is -3, and b is 7 we will impute the information. (you should get y= (-3x)+7)
I hope this helped. if you are still stuck i recommend using a khan academy video, those helped me when i learned this in 6th grade. Good luck. i recommend putting the formula on a paper as a reference guide to help in the future.
