What is the slope of the line? .

Answer:
[tex] - \frac{4}{1} or \: - 4[/tex]
Step-by-step explanation:
to find slope you have to do rise-over-run
rise means up and down
run means left and right
if the line goes to the left then it has a negative run with a positive rise
if the line goes to the right then it has a positive run with a negative rise
