Answer:
[tex]m = -3[/tex]
Step-by-step explanation:
-To determine the slope of the red line on the graph, you need the slope formula:
[tex]m = \frac{y_{2} - y_{1}}{x_{2}- x_{1}}[/tex]
-Since the red line shows it's decreasing, then the number will be negative. So, l picked [tex](0,3)[/tex] and [tex](1,0)[/tex] for the slope formula:
[tex]m = \frac{0 - 3}{1 - 0}[/tex]
Then, solve:
[tex]m = \frac{0 - 3}{1 - 0}[/tex]
[tex]m = \frac{-3}{1}[/tex]
[tex]m = -3[/tex]
so, the slope is [tex]-3[/tex].
