Question 635132: Is there a relationship between the sign (positive or negative) of the slope of a line and the angle the line makes with the x-axis?
For example, if you graph y = 3x+5, versus the graph of y = -3x+5

Hi,

y = 3x+5  (Green Line)

y = -3x+5  (Blue Line)

Lines with negative slopes... slant to the left, thus a larger angle is formed with the x-axis

Yes, size of the angle formed with the x-axis is related to the sign of the slope
