I'll just name the lines as A, B, C, D, E.
A : Corresponding angles
B : Alternate Interior angles
C : Co - Interior angles
D : Vertical angles
E : Alternate Exterior angles
Answer: 
Step-by-step explanation:
You can observe in the figure that JK is a tangent and KH is a secant and both intersect at the point K. Then, according to the Intersecting secant-tangent Theorem:

You know that:

Then KE is:



Now you can substitute the value of KE and the value of KH into
and solve for JK. Then the result is:
Answer:
The equation is 
Step-by-step explanation:
Observing the graph
Let

step 1
Find the slope m

step 2
Find the equation of the line into point slope form

with the point
and the slope 
substitute


<span>1.) f(x)=x+1/5 is already in that form
</span>2.) f(x)=3/2x-1/2
