Answer:
y = -2x - 5
Step-by-step explanation:
The given slope, or m, is -2 and the given y-intercept, or b, is -5.
The y-intercept equation is y = mx + b, so by knowing this equation all you need to do is plug in the given slope and y-intercept
y = -2x - 5
Set h =11
11=-5t^2+25t+1
-5t^2+25t-10=0
Now use quadratic formula to solve for t
t=[-b+\-sqrt(b^2-4ac)]/(2a)
t= [-25+\-sqrt((25)^2-4(-5)(-10))]/2(-5)
t= .438sec and 4.562sec
