Question

The following table shows the relationship between the number of parks and the number of slides in the park.

Number of parks (x)	2	5	7
Number of slides (y)	20	50	70

Put the value that shows the relationship between the two variables as y = __ x

• A. 10

Answer 1

The correct option is A 10

Number of parks($x$)	2	5	7
Number of slides($y$)	20	50	70

For every value of x, we can see value of y becomes:
$y=10\times x$

∴ The relationship between the two variables will be $y=10x$
