Example 1Tables of Values & Plotting Linear Relationships

A table of values is created using the linear rule

y = 5x - 3

. Complete the table by finding the value of

y

when

x = 0

Common mistake: Sign error when multiplying negative values or applying the constant term.

Correct Answer:

-3

Worked Solution:

1. Substitute

x = 0

into the rule

y = 5x - 3

y = 5 \times (0) - 3

2. Evaluate the linear expression:

5 \times (0) - 3 = 0 - 3 = -3
