13. Four observations:
1. m<SWT = 90° (given)
2. QW = TW (given)
3. m<RWS = m<UWV (vertical angle pair)
4. m<RWU = 180° (straight angle)
Answer:

Step-by-step explanation:
First find the slope using the slope using the given points. Remember that the slope is the change in y over the change in x.

So now we have the equation
, and we need to find out what b is. We can do this by pointing a point (either one, but I'll use -1,2) into the equation

Rearrange the equation so it equals b

Put it together and that's the final equation!

Answer:h=f(X)-x-k
Step-by-step explanation:
F(x)=x+ h+k
h = F(x)-x -k
