What does the slope of a line indicate about the line?

The slope of the line tells us the rate of change of y relative to x. ... If the slope is zero, then the line is horizontal and y does not change at all (the equation of the line has the form y = c and y = c for all values of x.)

Hi i just wanted you and me and you are a nice right off my mind and

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
