The first thing you may want to do would be to find the tangent line to the function. The tangent line is a line that passes through a given point on a function, but does not touch any other point on the function (assuming the function is one to one). Assuming you have the tangent line, the normal line is simply perpendicular to the tangent line- it forms a 90 degree angle with the tangent line.

One you have the tangent line and the point which it passes through, you can find the normal line. To obtain the perpendicular line to any function, take the inverse reciprocal of the slope (if your slope was 2, it is now -.5). After that, plug in your (x, y) coordinate, and you can solve for the constant b (assuming there is one).

This should give the normal line to a tangent of at a point on a function.

What is a line that intercects a circle at one point?

Generally, the equation of a circle is (x-a)2 + (y-b)2 = r2where (a,b) is the centre of a circle, and r is the radius.So you can use this equation along with a general line equation, y=mx+c, or using the gradient and finding the equation of the normal.

Which is an equation of a verticle line?

A vertical line can not be defined by any normal equation, because its range is a single number that gives the x-coordinate and y can have any value whatever.


What is the equation of the line that is perpendicular to -x y 7 and passes through -1 -1?

Without an equality sign and not knowing the plus or minus values of y and 7 it can't be considered to be a straight line equation therefore finding its perpendicular equation is impossible.

What does solving the equation for a line tell us?

A line is represented by an equation. Each solution of the equation is a point on the line, and each point on the line is a solution to the equation. So the line is just the graph of the solution set of the equation.
