Let the circle with centre (a, b) be tangent to the y-axis.
Then, the radius of the circle must be b.
Therefore the equation of the circle is
(x - a)2 + (y - b)2 = b2
or x2 - 2ax + a2 + y2 - 2by = 0
Then 2x - 2a + 2ydy/dx - 2bdy/dx = 0
ie x - a + ydy/dx - bdy/dx
(y - b)dy/dx = a - x
so dy/dx = (a - x)/(y - b) or -(x - a)/(y - b)
Which point is not located on the xaxis or the yaxis of a coordinate grid?Read more:Which_point_is_not_located_on_the_xaxis_or_the_yaxis_of_a_coordinate_grid
up and down. the x goes left and right
.... then your graph is inverted.
The vertical y axis on the Cartesian plane is both negative and positive
We use y_y axes
step 1 first u should seclect the name independent and dependent veriables 2. take X axis ur independent veriable and Yaxis as a dependent veriable 3.lable the axis with units 4. now draw all points on the paper 5.connect first and last point of the reading 6. make sure that u have slected a suitabe scale for drawing the graph of a complecated data
The main vertical line going up the middle is generally refered to as the y axis, while the horizontal line that meets the yaxis in the middle is refered to as the x axis. the line that's going up the line that's going across is the x axis
On graph paper. The horizontal line is the x-axis. The vertical line is the y-axis. Where the two line intersect is deemed to be the origin, and given the co-ordinates , in (x,y) form , of (0,0).
=== === A vertical line is a line with an undefined slope. Note that this is different from an infinite slope. The slope of a vertical line is said to be undefined. It may be said to go "straight up and down"A vertical line is drawn on a graph by plotting x = nwhere n equals any real number. The value of n is located on the x axis and then a line is drawn parallel to the yaxis through that x value. Note that the y axis itself is a vertical line. There are an infinite number of possible lines with an undefined slope, of course. Any number on the x axis can have a line drawn through it parallel to the y axis, and any one of those lines is said to be a vertical, and will have a slope that is undefined.A simpler definition say a vertical a line is a line that goes up to down
