Answer 1

The table that represents a proportional relationship is:

x = -1, -3, -5

y = 1, 3, 5

Which table represents a proportional relation?

A proportional relationship is written as:

y = k*x

Where k is the constant of proportionality.

Notice that for equidistant increases in x, we should have equidistant increases on y. Also, proportional relations always have the point (0, 0)

Then the table that represents a proportional relationship is:

x = -1, -3, -5

y = 1, 3, 5

Where the proportional relation is:

y = (-1)*x

When x = -1

y = (-1)*(-1) = 1

When x = -3

y = (-1)*-3 = 3

When x = -5

y = (-1)*(-5) = 5

So the correct option is the second one.
