The equation represented by the graph is expressed as: Option B. y = 2.5
What is the equation that represents a line?
The graph is a horizontal line that cuts the y-axis at y = 2.5, it means that for every value of x, the corresponding y-value is always 2.5.
The equation of a horizontal line is of the form y = c, where c is a constant representing the y-intercept. In this case, the y-intercept is 2.5.
Therefore, the equation is y = 2.5, indicating that the y-value is always 2.5, regardless of the x-value.
