Answer:
-12
Step-by-step explanation:
The y-intercept is a point where the graph of a function intersects the yaxis. This happens when x=0. So to solve this problem simply insert x=0 into the equation [tex]y = \frac{x}{5} -12 = > y = \frac{0}{5} -12 = 0-12 = -12[/tex]
Now I'm not sure why it's asking for the value of b, as it should ask for the value of y but the answer nonetheless ought to be -12
