2変量の線形方程式の一般的な例は、労働時間と稼いだお金の関係に見られます。1時間あたり10ドルを稼ぐと、Y = 10xはX時間後に稼いだ金額の合計金額を表します。Yインターセプトは、時間がなかったときに稼いだ量を表します（この場合は0）。X interceptは、お金が稼いでいないときに労働時間数を表します（この場合も0）。勾配は、労働時間ごとに稼いだお金の変化率を表します（この場合は10）。
A common example of a two-variable linear equation can be seen in the relationship between hours worked and money earned. If you earn $10 per hour, then y = 10x represents the total amount of money earned after x hours. The y-intercept represents the amount earned when no hours have been worked (0 in this case). The x-intercept represents the number of hours worked when no money has been earned (also 0 in this case). The slope represents the rate of change in money earned for each hour worked (10 in this case).
