Interactive lesson with video explanation of how to find the slope of a line given two points or its graph whether the slope is positive, negative or undefined or the line is vertical or horizontal.
Thus, the slope of a vertical line is undefined. A vertical line intersects a horizontal line at a right angle.Equation of a Vertical LineThe equation of a vertical line in math can be given by x = ± a, where (a,0) is the x-intercept, the point where the line intersects the x-...
When the slope is equal to zero, we say that there is no slope. 4. Undefined Slope Description: The line is vertical, with no horizontal change. In other words, you areonlymoving up or down. Real-Life Example: Attempting to climb a sheer vertical cliff ...
determine whether the slope of each line is positive,negative,zero,or undefined.1.the line passes through the points (a,d) and (a,c)2.the line passes through the points (x,y) and (x+a,y+a)3.the line passes through points (-x,y) and (x,-y)应该是1.the line passes through th...
Find the rise (the length of a segment on the y-axis): The rise (the length of the vertical blue line) in the above picture is 4. Find the “run” (the length of a segment on the x-axis): The run (the length of the horizontal blue line) is 2. ...
The equation of a horizontal line (a line parallel to the x-axis) is found using the general equation: y = b, where b is the y-coordinate of any point lying on the line. Similarly, the equation of a vertical line (a line parallel to the y-axis) can be given as: x = a, ...
In mathematics, the slope of a line tells us how quickly the line is rising or falling, and we have many different rules and properties regarding slopes of different types of lines. Two such rules are that the slope of any vertical line is always undefined, and that the slopes of two...
Example 2: Find the slope of the straight line that passes through (1, -4) and (-1, 3) or state that the slope is undefined. Then indicate if the line through the points rises (left to right), falls (left to right), is horizontal, or is vertical. Is horizontal the same as ...
If the slope of a line is zero, assuming x=-4 has a slope of zero since it is a straight line, does that make it undefined? What kind of line has a slope that is undefined? Is zero slope horizontal or vertical? Does an undefined slope equal zero? What is the slope of an undefin...
When the slope is negative, the line leans to the left. When the slope is positive, the line leans to the right. When the slope is zero, it means that the line is horizontal. When the slope does not exist or is undefined it is a vertical line....
