How do I write the linear equations. Please help ASAP THANK YOU

Well there is no linear equation that represents y as a function of x. You said it yourself, "The data CANNOT be modeled by a linear equation because the rate of change is not constant."

Step-by-step explanation:

There is none. y has random values.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
