3.    Which statement best represents the equation of the line shown on the grid and its relationship to the x-axis?

• The equation of the line is x = 2.5, and the line is parallel to the x-axis.

• The equation of the line is x = 2.5, and the line is perpendicular to the x-axis.

• The equation of the line is y= 2.5, and the line is parallel to the x-axis

• The equation of the line is y = 2.5, and the line is perpendicular to the x-axis.

6. 6. Write the equation that is perpendicular to and passes through the point. Your final equation must be in slope-intercept form.
