A line that is vertical has an undefined slope. In this case, there is no “run,” and x2 – x1 = 0. Thus, m = y2–y1 /x2–x1 = y2–y1/ 0, and any fraction with 0 in its denominator is, by definition, undefined. ? A line that makes a 45o angle with a horizontal lin...

Parallel Lines Parallel lines – lines in the same plane that do not intersect. Parallel lines have the same slope. All vertical lines (with an undefined slope) are parallel. If the graph of the equation y=4x-5 is parallel to another line, they both have a slope of 4. Perpendicular Lin...
Its slope is 0. Its slope is undefined. Its equation is of the form y = b where (a, b) is any point on the line. Its equation is of the form x = a where (a, b) is any point on the line. It doesn't move vertically. It doesn't move horizontally. It is parallel to the...
Reviewing types of slope Remember, there are four types of slope: PositiveNegative No slope Undefined slope The slope of a line The slope of a nonvertical line passing thru the points (x 1,y 1 ) (x 2,y 2 ) : Find the slope of a line passing thru (-3,5) & (2,1) ...
What is the slope of the line is vertical? Zero slope means that the line is horizontal: it neither rises nor falls as we move from left to right. Vertical lines are said to have"undefined slope," as their slope appears to be some infinitely large, undefined value. ...
In the case where one of the lines is vertical, the slope of that line is undefined and it is not possible to calculate the product with an undefined number. When one line is vertical, the line perpendicular to it will be horizontal, having a slope of zero (m=0m=0)....
Responses can also be moved by dragging with a mouse. Equation of a vertical line passing through the point (-3,2) Slope of x = 3 Equation of the vertical line passing through (3,2) undefined x = 3 x = - 3Check Answer Q 2. Choose true or false. TrueFalse The slope of the ...
Because of this fact, it is said that the slope of this vertical line is undefined. This is true for all vertical lines—they all have a slope that is undefined.Example What is the slope of the line that contains the points (3,2)(3,2) and (−8,2)(−8,2)? Show Solution ...
When the angle with + ve x-axis ‘tan θ’ is called the slope of a straight line. Note 1 – If the line is horizontal, then slope = 0 Note 2 – If the line is perpendicular to the x-axis, i.e., vertical, then the slope is undefined. Slope = 1/0 = ∞ = tan π/2...
