Answer:
m= [tex]-\frac{1}{3}[/tex]
Explanation:
Formula is Y=mx+b
m equals the slope (rise/run each point).
x stays for an ongoing function.
b is the y intersect(You'll see that the line crossed +4 on the vertical line).
Looking at the line from left to right, it starts from the top to the bottom instead of button to top. If this slope goes down, it is negative.
[tex]y=-\frac{1}{3}x+4[/tex]
That is why [tex]m=-\frac{1}{3}[/tex] instead of [tex]m=\frac{1}{3}[/tex]
