Which statement is true?

• All lines have a positive slope.
• A line that contains points in Quadrant I and Quadrant III must have a negative slope.
• A line that rises as you move to the right along the line has a positive slope.
• A horizontal line has no slope.

Which of the following is the equation of a line with a slope of 6 and a y-intercept of −3?
