C. The three angles on the bottom are all exactly the same.
K+3=-9
k=-12 is the answer
Answer:
<h2>D. 3</h2>
Step-by-step explanation:



Mark points in the coordinate system.
Lead a line through these points.
Read x-intercept.
We know that
A relationship between two variables, x, and y,<span> is proportional if it can be expressed in the form y/x=k or y=kx</span>
in this problem
k=2
then
y=2x
therefore
the answer is the option
y=2x
