Which equation best represnt the line of best fit?
A. y=-16x+400
B. y=-15x+300
C. y=15x+-300
D. y=16x+400
+118687 I don't intend to give you just the answer. I am not here to do your homework but I am happy to help you learn.
*Is the gradient of this line positive or negative. Which choices are ruled out?
*What is the approximate y intercept? Which choices are ruled out?
Which choices are left?
Now by visual inspection, which is the best choice :)
If you want to interact with me I will help you work through it :)
+90 Well when i was waiting for your response, i did and tried the probelm myself, first, drawing the line of best fit, choose two good y-intercepts, did the m=y2--y1/x2-x1 and got -16. After that the probelm started to become weird. I chose a piar of coordinates and use it in the equation y=mx+b, pluging in the numbers and solving it. The answer i got was y=-16x+1324, which was sort of close to one of the answer choses.

Question is: Which equation best represnt the line of best fit?
A. y=-16x+400
B. y=-15x+300
C. y=15x+-300
D. y=16x+400
+118687 ok, you got a gradient of about -16. It is definitely negative anyway because it slopes to the top left corner, so which anwer/s do younow know are definitely wrong?
Which answers are now still possibly correct?
What might the y intercept be approximately? Which answers does this rue out?
What answers are left now?
HINT:
remember that the equation of a line is y=mx+b
where m is the gradient and b is the y intercept
