anonymous · Answer

is the slope positive or negative?

anonymous · Answer

Positive?

anonymous · Answer

is the graph going up or down. (left to right)

anonymous · Answer

right to left

anonymous · Answer

the graph is going down as the line goes from left to right. That means it is negative slope

anonymous · Answer

I think its B

anonymous · Answer

so that leaves us with 1 and 3. The next question is the y-intercept

anonymous · Answer

what is it?

anonymous · Answer

B is correct, since the slope is negative and the y-intercept is -1
