Well, since a tangent line touches a line in one spot, the Y axis could be considered tangent to the X axis.
The x-axis is the horizontal axis on a graph. The y-axis is the vertical axis on a graph.
In a Cartesian grid, the x-axis is the horizontal axis, and the y-axis is the vertical axis.
Equation of circle: x^2 +y^2 -6x +4y +5 = 0 Completing the squares (x -3)^2 +(y +2)^2 = 8 Centre of circle: (3, -2) Radius of circle: square root of 8 Points of contact are at: (1, 0) and (5, 0) where the radii touches the x axis Slope of 1st tangent line: 1 Slope of 2nd tangent line: -1 Equation of 1st tangent: y -0 = 1(x -1) => y = x -1 Equation of 2nd tangent: y -0 = -1(x -5) => y = -x +5
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)

The y-axis is the vertical axis on a graph.
[1+(y')2]3 = [yy"+1+(y')2]2

It is Y.
dy/dx = (r - x)/sqrt(2xr - x2) , I hope!
The slope of a line and the tangent of the angle between the positive x-axis and the line are related because the tangent of the angle is defined as the ratio of the y-coordinate and the x-coordinate of some point on the line.
The vertical axis in a graph.
y = -2x + 5 Slope is -2, that is the angle the line makes with the x-axis is such that tangent of that angle is -2 The y-intercept is 5
