Which equation represents the graph of the linear function?
a. y = −2x+ 1
b. y = −2x − 1
c. y = 2x + 1
d. y = 2x − 1

I think you forgot to attach the graph along with the question. I am answering the question based on my knowledge and research. "y = −2x − 1" is the one equation among the following choices given in the question that represents the graph of the linear function. The correct option among all the options that are given in the question is option "B".

There should only be 1 solution
