The given equation is y = 0.85.

This equation represents a straight line with a slope of 0 and a y-intercept of 0.85. The slope of 0 indicates that the line is horizontal, meaning that the y-value remains constant for all x-values. The y-intercept of 0.85 indicates that the line intersects the y-axis at the point (0, 0.85).

Therefore, the line represented by the equation y = 0.85 is a horizontal line that passes through the point (0, 0.85).
