Can someone explain this to me and tell me the answer please?

Answer:
Last one: y = -6x-1
Step-by-step explanation:
If you graph the point (-1,5) and go down 6, right 1, the y-intercept will be at -1. That is what -1 represents. The slope of -6 is in the coefficient for x. Therefore, the answer is y = -6x - 1. Hope this helped.
