2016年7月9日 · Vertical lines are parallel to the y-axis and pass through all points in the plane with the same x-coordinate. Since it goes through the point (-4 ,-3) then it will pass through x = -4 , hence the equation of this line is x = -4. Horizontal lines are parallel to the x-axis and pass through all points in the plane with the same y-coordinate.

A vertical has the equation #x=c# with #c# any constant number. A normal linear equation is mostly of the form #y=mx+b# where #m# is the slope. In a horizontal graph, the slope is 0. The #b# (called the #y#-intercept) tells you where the graph crosses the #y#-axis. For the vertical graph a similar story goes and #c# is called the #x#-intercept.

2017年1月9日 · See full explanation below For a vertical line the value of x, in this case color(red)(8), will never change. This will be true for any value of y. Therefore the equation for a vertical line passing through this point is: x = 8 Likewise, for a horizontal line the value of y, in this case color(red)(-7), will never change. This will be true for any value of x. Therefore the …

2016年9月10日 · The horizontal tangent lines have #f_x = 0->x = -y/2# and the vertical tangent lines have #f_y = 0->x = -2y# So for horizontals. #f(-y/2,y) = y^2/4-2y^2+y^2-27=0->y=pm6# and for verticals. #f(x,-x/2) = x^2-x^2/2+x^2/4 - 27=0->x=pm 6#

2017年5月23日 · The equation of the horizontal line passing through (4,7) is y=7. Equation of a horizontal line line is always of the type y=k As in the pint (4,7) ordinate is 7 the equation of the horizontal line passing through (4,7) is y=7. Note - The equation of a vertical line is always of the type x=k and hence the equation of the vertical line passing through (4,7) is x=4.

2017年1月14日 · What would the #(x,y)# table look like for a horizontal and a vertical line graph? How do you graph #y=4#? What are some examples of when you would see horizontal or vertical line graphs?

2015年3月29日 · A graph of a 1-1 function needs to pass both the vertical line test and the horizontal line test. A graph will represent a function, if any vertical line drawn crosses it only once. If the function is also 1-1, then any horizontal line drawn will cross it only once. If the horizontal line crosses the graph more than once, the function is not 1-1.

2018年5月7日 · What would the #(x,y)# table look like for a horizontal and a vertical line graph? How do you graph #y=4#? What are some examples of when you would see horizontal or vertical line graphs?

2018年3月18日 · What is the slope of a horizontal tangent line? How do you find the slope of a tangent line using secant lines? See all questions in Tangent Line to a Curve

2015年7月27日 · No, in some sense they have no slope, but if you'd want to assign a slope to it, it would be pmoo. Almost every line on an x,y plane can be described by y=ax+b. Here a is called the slope of the line, and b is the y-coordinate where the line crosses the y-axis. If it has a slope 0, this would give y=b, so a horizontal line. Alternatively, every horizontal line has the form y=b, …
