If a line has an undefined slope what can you say about the horizontal coordinates of each of the points on the line?
A vertical line has an undefined slope. If a line is vertical, the horizontal coordinate, commonly known as the x coordinates, must all be the same. If not, the line would not be vertical.
How is slope of a straight line calculated?
The slope of a straight line is calculated by taking the difference in the y-coordinates (rise) of two points on the line and dividing it by the difference in the x-coordinates (run) of the same two points. This is expressed mathematically as ( m = \frac{y_2 - y_1}{x_2 - x_1} ), where ( m ) is the slope, and ( (x_1, y_1) ) and ( (x_2, y_2) ) are the coordinates of the two points. A positive slope indicates the line rises from left to right, while a negative slope indicates it falls. If the line is horizontal, the slope is zero; if vertical, the slope is undefined.
How do you find the slope intercept and standard forms of a line when the slope is undefined and you are given the coordinates 2 and 4?
When the slope is undefined, you know the line has to be vertical. Vertical lines only have an x in their equations. When you have the coordinates (2,4) with a vertical line, the equation for the slope intercept AND standard form would be the same thing: x=2
How can you tell that the line segment connnecting the points is vertical without graphing the points?
The equation does not have and y variable in it: it is of the form x = c. Alternatively, the x coordinates of both points are the same and the y coordinates are not.
What is the slope of the line through the pair of points -7-8 and -7-3?
The line is vertical on the graph. Its slope is infinite.

Does a vertical line have a slope of 0?
No. A horizontal line has a slope of 0. A vertical line has an undefined slope. Let's say you have a vertical line with the points (3,-2) and (3,4). The slope is (y1-y2)/(x1-x2) = (-2-4)/(3-3) = -6/0 = undefined. Notice that x is the same for both points. A line in which all points have the same value for x is a vertical line and as such has an undefined slope.
What do you need to use the point slope formula?
The slope of a line and the coordinates of a point on the line.The slope of a line and the coordinates of a point on the line.The slope of a line and the coordinates of a point on the line.The slope of a line and the coordinates of a point on the line.

Is the slope always positive if the coordinates of two points on the line are positive?
No.
What is the slope of the line containing the points (6 4) and (6 8)?
Points: (6, 4) and (6, 8)Slope: 0 because it is a vertical straight line that is parallel to the y axis
What is the slope of the line through the pair of points -7-8 and -7-3?
The line is vertical on the graph. Its slope is infinite.
What slope does vertical line have?
A vertical line has a slope of infinity.
What is the slope of the line that contains the points (83) and (87)?
Points: (8, 3) and (8, 7) Slope: 0 It will be a straight vertical line parallel to the y axis
Slope of a vertical line?
The slope of a vertical line is undefined. Horizontal slope is 0.
How do you find the slope of the line which passes through the points with coordinates?
y=mx+b
