Problem

3. In one linear function, when you subtract each y-coordinate from the x-coordinate, the difference is 3. If the x-coordinate is not greater than 10 and the y-coordinate is a positive whole number, how many ordered pairs are there?

Solution

Here are the conditions

x- y= 3

x <10

y >0

And then we have these as possible answers:

4-1 =3

5-2= 3

6-3=3

7-4=3

8-5=3

9-6=3

Then the total possible pairs are: 6
