If someone answers this I'll give brainliests because I have been trying for so long question: what is the rate of change for y= -3x

Rate of change, or slope, is 0.

Step-by-step explanation:

Normally, we would say that the number with the -3x if there was one, would be called B but seeming as there is no number, I can only assume that the rate of change is 0. So the point would be (0,0).

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
