What is the direct variation equation for the table of ordered pairs?

Question

x y
4 4.8
8 9.6
11 13.2



Question 5 options:

y = 1.2x

y = 3.5x

y = 0.8x

y = 4.8x

Answer 1

To determine the direct variation equation, we need to find the constant ratio between the x-values and the y-values.

For the first pair of ordered pairs (4, 4.8):
y/x = 4.8/4 = 1.2

For the second pair of ordered pairs (8, 9.6):
y/x = 9.6/8 = 1.2

For the third pair of ordered pairs (11, 13.2):
y/x = 13.2/11 = 1.2

Since the constant ratio is always 1.2, the direct variation equation for the table of ordered pairs is y = 1.2x.

Therefore, the correct option is:

y = 1.2x
