Answer:
-5
Step-by-step explanation:
The y coordinate of the vertex is -5.
Y=t(15)+4 Is what I think this word problem would be written in Slope-intercept form.
Start with
Separate the variables:
Integrate both parts:
Which implies
Solving for y:
Since 
is itself a constant, let's rename it 
.
Fix the additive constant imposing the condition:
So, the solution is
