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 do you find slope and y-intercept?
Slope of vertical and horizontal linesThe slope of a vertical line is undefined. This is because any vertical line has a x or "run" of zero. Whenever zero is the denominator of the fraction in this case of the fraction representing the slope of a line, the fraction is undefined. The picture below shows a vertical line (x=1)The slope of a horizontal line is zeroThis is because any horizontal line has a . Y or "rise" of zero. Therefore, regardless of what the run is (provided its' not also zero!), the fraction representing slope has a zero in its numerator. Therefore, the slope must evaluate to zero. Below is a picture of a horizontal line...you can see that it does not have any 'rise' to it.Formula to find the slope of a lineExample 1of the Slope of A lineThe slope of a line through the points (1, 2) and (2, 5) is 3 because every time that the line moves up three (the change in y or the rise) the line moves to the right (the run) by 1.Illustrated Example TwoThe slope of a line going through the point (1,2) and the point (4,3) is 1/3.
What is the slope of y equals -13?
0A line with the equation y = -13 is a horizontal line. The slope is zero.If you think of the "y = mx + b" form of a straight line, the 'b' must be -13, and the 'm' must be zero since there is no x term. 'm' is the slope, so the slope is 0.
How do you tell if lines are perpendicular based on slope?
The slope (rise over run) of one line will be a number (n) or (-n) and the perpendicular line's slope will be the exact opposite. So, for instance, if one line has a slope of 2/3, then a perpendicular line's slope must be -2/3, and vice versa.
Undefined index in PHP?
Please focus on the line number before the line of the error. There must be an array, with some issues with the index.
A line parallel to another line with an undefined slope must also have an undefined slope?
Sounds reasonable. If the lines are parallel, then their slopes are equal.
What is the difference between undefined slope and no slope?
Undefined slope is when a line is exactly on the y-axis, for reasons unknown, the slope of a line on the y-axis cannot be determined, so therefore it it "undefined." A line with no slope is a line with a slope of zero. In order for a line to have a slope of zero, it must be directly on the x-axis, meaning it is horizontal. Horizontal lines are straight and have no slope
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.
The slope of a line is undefined What is the slope of the line that is perpendicular to it?
Perpendicular lines = Right Angles, thus any right angle related things work, and you know the angle of one of the 3 (90 degrees) so the perpendicular line as a slope of 90 minus the the angle of the undefined: Since the angles of a triangle must add to 180 Undefined + Perpendicular + Right Angle (90) = 180 Or something like that... been a while since I did geometry... hope this helps * * * * * A line with an undefined slope is a vertical line and so a line that is perpendicular to it is a horizontal line. In the coordinate plane, that would be a line with the equation y = c (for some constant c).
What must be true about the slope of a line whose graph extends into quadrants II and IV?
it is a negative slope.
If the equation of a line has an undefined slope and passes through the point 1 3 which form would be used to write the equation of the line?
x = 1 (the line intersects the x-axis at 1, and is parallel to the y-axis)We cannot write the equation on the Slope-intercept form, since the slope of the line is undefined. 1 is the x-coordinate of any point on the given line.
Is a line with undefined slope the graph of a function?
This is not a function. To be a function, there must be a one to one relationship between the independent variable (usually represented by the horizontal or x axis) and the dependent variable (usually represented by the vertical or y axis). A line with undefined slope is a vertical line, so there are an infinite number of possibilities for y and only one possible value of x, so this is not a function.

What is the slope of a line parallel to a line with slope -2?
For two lines to be parallel they must have the same slope. A line parallel to a line with slope -2 would have a slope of -2.
What is the slope of y equals -13?
0A line with the equation y = -13 is a horizontal line. The slope is zero.If you think of the "y = mx + b" form of a straight line, the 'b' must be -13, and the 'm' must be zero since there is no x term. 'm' is the slope, so the slope is 0.

What is the equation of a line in the slope is -7 through -65?
To work out the equation of a straight line the slope and an (x, y) coordinate must be given
