I believe that the answer is, D.
I think this because 1.8 is greater than -66%, -66% would be last i believe. I think -66% is least out of all of them.
Hope this helps ya.
Part A: There are 114 red marbles
Part B: There are 114 red marbles because if you multiply the ratio 19:1 times 6 you would get 114:6 (added together gives you 120)
Answer:
y=4x + 7
Step-by-step explanation:
Line=y=ax+b
b = where the line crosses the y-axis (where x=0). Here, it's 7.
a= vertical distance ÷ horizontal distance.
You can take any pair of distances to a point on the line, for example (4,1) is easy to read in the graph.
x=0 to 1 (horizontal distance=1-0=1)
and
y= 0 to 4 (vertical distance= 4-0=4)
a=4÷1=4.
So, the answer is y=4x + 7 as a= 4 and b=7.
