The equation \( y = 2x - 5 \) is indeed a linear relationship.
In general, a linear relationship can be expressed in the form \( y = mx + b \), where:
- \( m \) is the slope of the line,
- \( b \) is the y-intercept.
In this case:
- The slope \( m = 2 \),
- The y-intercept \( b = -5 \).
Since this equation fits the linear form, it represents a straight line when graphed. Therefore, it is a linear relationship.
