Answer:
k=5
Step-by-step explanation:
step 1
Find the equation of the line f(x)
we have the points
(-4,0) and (-2,2)
<em>Find the slope m</em>

Find the equation of the line in point slope form

we have

substitute


Remember that
f(x)=y
so

step 2
Find the equation of the line g(x)
we have the points
(-4,0) and (-2,-10)
<em>Find the slope m</em>

Find the equation of the line in point slope form

we have

substitute


Remember that
g(x)=y
so

Remember that
------> 
therefore
k=5
I believe it is a function
42 is the numerator you multiply 8 times 6 so you do the same with the top
Low August: 9 C or 9.4 C if you need specifics
Avg. August: 22 C or 21.66 if you need specifics
Y=-1/2x-8
This is in y intercept form
