Answer:
x + 3y = 21
Step-by-step explanation:

Equation of the line: y =mx+ b

Multiply the equation by 3
3y = -x + 21
x + 3y = 21
I only have the answer for 3 and i believe it is 20,090
3/5 = 60%
20 ÷ 5 = 4
3 x 4 = 12
Answer is A) 12/20

Multiplying by 1/4 is the same as dividing by 4
-36(1/4) = -36/4 = -9
