Mean Absolute Deviation I'm pretty sure. Hope this helped, have a great day! :D
Well if you add all the numbers together, the total is 14. So 4/14 chance of pulling out a red marble.
So an equation of any line is y=mx+b.
We know that the m, or slope, equals 3.
y=3x+b
Now we find the b, or the y-intercept, by substituting the x and y values into their places.
4=3*1+b
4=3+b
b=1
Now that we have the y-intercept, we just substitute the m and b into the equation and receive our final answer:
y=3x+1
