Given a function of f(x)= \frac{ax+b}{cx+d} match how you would solve for the following.

Draggable itemCorresponding Item
x-intercept
Let the bottom equal to zero
cx+d=0
Horizontal Asymptote
Divide the coefficient of the top by the bottom if they are the same power
\frac{a}{c}
y-intercept
Plug in 0
\frac{a\cdot 0+b}{c\cdot0+d}
This does nothing
Set the top equal to zero

ax+b=0
Vertical Asymptote
Take the sum of a and c and divide by the sum of b and d
\frac{a+c}{b+d}
