Please type your <u>subject</u> in the <b>School Subject</b> box. Any other words are likely to delay responses from a teacher who knows that subject well.

Answer 2

Each unit increase of the top row variable (x) increases the bottom row variable (y) by 3. Therefore it is a linear relationship, of the form
y = mx + b,
with a slope m = 3.

You should be able to figure out what "b" is, using any pair of numbers from the table.
