Opened at both end =

Step-by-step explanation:
Answer:
Step-by-step explanation:
Direct variation has the form y=kx, given k=7 and x=20
y=7(20)=140
Points: (0,4) and (2,-3)
Find slope: (-3-4)/(2) = -7/2
4 = -7/2(0) + b, b = 4
Equation: y = -7/2x + 4
B)7:8 is the answer because:
16 total - 7 green = 8 and so
the ratio of GREEN to RED is
7:8
7 green 8 red
For a) it would be 1:2 as it is 16:8 and simplified would make it 1:2
