Answer: y=-1/3x+5

Step-by-step explanation: I presume they want this in the y=mx+b format where m is the slope (change in y/change in x) of the line and b is the y-intercept (what y is when x is equal to 0). To answer this you need to choose any 2 points on this graph. For simplicity's sake, I'm going to choose (0,5) and (9,2). What's good about choosing (0,5) is that we now know the y-intercept is 5. Now, to find slope, subtract the y coordinate 2 from the y coordinate 5. You now know that the change in y is 3. Then, subtract the x coordinate 9 from the x coordinate 0. You now know that the change in y is -9. Finally, divide 3 (change in y) by -9 (change in x) and you should get -3/9 which can be simplified into -1/3. So now that you have your y-intercept and your slope, all that's left to do in plug it into the format. So your answer should be y=-1/3x+5. Hope this helps you!

Answer:

2494.756kg

*see below regarding significant digits

Step-by-step explanation:

Set up a grid to help you to know whether to divide or multiply. Stack equivalent values one on top of the other in your grid. Arrange them so that the units will cancel out. This helps you to change the units. See image.

*if you are also learning about "significant digits" then you will have to alter the answer to only include the same number of significant digits as in the question.

The exact calculated answer is 2494.756, but there are only two significant digits in the question, so the answer maybe 2500kg instead. If your teacher hasn't taught sig figs then go with the exact answer.

2494.756kg
