Question

What are the possible values of x and y for two distinct points, (5, –2) and (x, y), to represent a function?

The value of x can be
.



The value of y can be
.

Answer 1

The value of x can be 10

The value of y can be -4

Explanation:

Assume the function is linear of the form
y = mx

When x = 5, y = -2

Simply multiply x by 2 and equivalently multiply -2 by 2

x = 5 x 2= 10

y = -2 x 2 = -4
