A vertical line is one that is parallel to the y-axis of a graph. A vertical line is also perpendicular to the x-axis of the same graph, which means that the value of the x-coordinate for a vertical line does not change.
Know MoreA vertical line can be verified by checking the x-coordinate of that particular line. Any vertical line has the same value of x-coordinate throughout, which means that any two points on that line will have the same value of x-coordinate. When drawing a vertical line, you should get the value of x-coordinate for the line by putting the value of y as 0 in the equation of the line to get the x-intercept of the line. After getting the value of the x-coordinate, simply mark that point on the x-axis and then draw a straight line perpendicular to the y-axis to this point. Such a line will be parallel to the y-axis of the graph and, therefore, according to the definition of vertical lines, will be a vertical with respect to this graph. A vertical line has no slope, which can easily be proved as the value of x-coordinate of the line is same all along its path.
Learn more about GeometryAccording to the Math Planet, a coordinate plane is a two-dimensional number line that is composed of a horizontal line called the x-axis and a vertical line called the y-axis. These two lines are perpendicular with each other and intersect at a point called the origin.
Full Answer >In the Cartesian Plane, the slope of a graph represents the rate of change of the graph. The slope of graph at any given point is the point's "y" value (rise) divided by the "x" value (run).
Full Answer >Examples of vertical angles in real life settings include the black and white railroad crossing signs found on roadways near railroads, open scissors and the letter "X." Other examples include the point where ceiling beams intersect in a somewhat x shape, and in a kite where two wooden sticks hold it together.
Full Answer >Diminishing returns is graphed by assigning the input factor to the x-axis and assigning the output, or product, to the y-axis. The total product curve is the total number of units produced per units of input. The marginal product curve is the marginal product generated per units of input. Diminishing returns is reflected at the point where the marginal product curve has a negative slope.
