Look at the graph below.

a. Copy and complete the table of coordinates.

b. Describe in words the relationship between the x- and y-coordinates.

The y-coordinate is always 1 less than the x-coordinate.

c. Write your rule using algebra.

y = x −1

d. Does the point with coordinates (10 , 9) lie on the line? Justify your answer.

Yes it does. The equation of the line is y = x −1. If we substitute the x- and y-values of the coordinates into the equation, it is correct.

That is 9 = 10 – 1 ✓
