Do you know how to write one?

anonymous · Answer

You can test the four rules given by plugging in three of the x values into each.

no i dont and i still dont get it

anonymous · Answer

If you plug a value of x into the equation, you should get the corresponding value of y when you simplify the equation.

ok thanks

A "linear relation" is a relationship which, when graphed, forms a line. To check if these points do, you can plot them on graph paper or test a linear formula to see if it hits every point..
