medium box has best value
Answer:
Step-by-step ex snsmsndjsnshsushdidjdplanation:
To solve the question, use the equation y=mx+b. Since you already know the slope (m), all you need is to find the b. Plug in the x and y from the point (9,2) and m:
2=3(9)+b
2=27+b (subtract 27 on both sides)
b=-25
The equation is y=3x-25
The first one is distributive property.
