WitrynaPositive slope Here, y increases as x increases, so the line slopes upwards to the right. The slope will be a positive number. ... The slope of any horizontal line is always zero. The line on the right goes neither up nor down as x increases, so its slope is zero. Undefined slope When the line is exactly vertical, it does not have a defined ... WitrynaThe function would be positive, but the function would be decreasing until it hits its vertex or minimum point if the parabola is upward facing. If the function is decreasing, …
WitrynaThe slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0). because division by zero is an undefined operation. Witryna2 lis 2010 · The slope of a line is always positive, no matter which way the line is angled or heading. Properties of a slope? The slope of a line can be determined by examining the graph; only one line through a point has a particular slope.
