Yanka [14]
The correct answer is 12/20.

If you multiply the numerator and the denominator of 3/5 by 4/4:

3•4 = 12
————-
5•4 = 20

Therefore, the equivalent of 3/5 is 12/20.

Answer:

C = n + 2

Step-by-step explanation:

Well looking at the line on the graph we can see that the y intercept is 2 because the y intercept is the point in the line that touches the y axis.

And the slope is how fat away each points are from each other on a line so we can find the slope by using two points on the line, we can use (1,3) and (2,4).

So we set up the formula like this \frac{y^2-y^1}{x^2-x^1}.

And now we gotta plug in the numbers and solve so the answer is 4-3 = 1 and 2-1 = 1 so the slope is 1.

And we can’t write that as just n.

So the answer is C = n + 2.

For proof look at the image below.
