The answer is either A or D, B and C are off the table because the two shapes need to be graphed for those to be relevant. The answer you get should be A I believe.
Answer:x=20/y
Step-by-step explanation:
x α 1/y
removing the constant of proportionality sign α and replace it with =k
x = k/y
x=10 y=2
10 = k/2
Cross multiply
10x2=k
20=k
k=20
Substitute k=20 in x=k/y
x=20/y.........required equation
Use the formula y=mx+b in order to solve for b. Then, plug in known values.
Answer: y= -4x-13, which is G on your worksheet.
