We are asked to find the slope of the line that is parallel to the line
.

- Parallel lines have the same slope.
So let's first determine the slope of the first line, and then let's find the slope of the line that's parallel to it.

- The slope is the coefficient of x.
So the slope is
.
Can you guess the slope of the line that is parallel to the first line?
That's right! The slope is...

Hope it helps you out! :D

Answer:
B
Step-by-step explanation:
On the graph we have points x:y of
3:5
6:10
12:20
which are all in the ratio 3:5, a slope of 5/3.
3:5=9:y
y=9×5/3 = 15
Answer: C (9,15)
