So, the line and the plane are neither orthogonal nor parallel. So let's work out what b must be-- or what b, the y-intercept, this is a lowercase b, not the line B. We know that y is equal to negative 7 when x is equal to 6.

So, for all our efforts on this problem, we find that the slope is undefined and the y-intercept does not exist.

The graph would look like this: A review of the main results concerning lines and slopes and then examples with detailed solutions are presented.

Since both of these are in the plane any vector that is orthogonal to both of these will also be orthogonal to the plane. If your device is not in landscape mode many of the equations will run off the side of your device should be able to scroll to see them and some of the menu items will be cut off due to the narrow screen width.

And this is the equation of the line in point slope form if you wanna put it in slope intercept form. The general equation of straight line is given by: Another way to look at this is the x value has to be 0 when looking for the y-intercept and in this problem x is always 5.

Suppose the weights of the masses are w1, w2, w3, And we are done. For an interactive exploration of this equation Go here. The angle of rotation is 90 degrees because a perpendicular line intersects the original line at 90 degrees.

In our problem, that would have to be 2. The concept of the moment of a force comes from the law of the lever, discovered by Archimedes. It goes through this point right there. Note how we do not have a y. And instead of being a negative, it's going to be a positive.

It is completely possible that the normal vector does not touch the plane in any way. Due to the nature of the mathematics on this site it is best views in landscape mode.

We wish now to deal with the problem of computing the location of the center of gravity, or center of mass, of a body. Equivalently, a different quantity may be used, termed the energy of the curve; minimizing the energy leads to the same equations for a geodesic here "constant velocity" is a consequence of minimization.

A line is parallel to another if their slopes are identical. In particular, the path taken by a falling rock, an orbiting satelliteor the shape of a planetary orbit are all geodesics in curved spacetime.

And they tell us that line A has an equation y is equal to 2x plus Well you know that having a 0 in the denominator is a big no, no.

This is another interactive tutorial on the slope of a line. This is a vertical line with undefined slope and passes through all points with x coordinate equal to h.

It's negative 3, is equal to negative 3 plus our y-intercept. Note that all the x values on this graph are 5. Show Solution This is not as difficult a problem as it may at first appear to be. Also notice that we put the normal vector on the plane, but there is actually no reason to expect this to be the case.This calculator find and plot equations of parallel and perpendicular to the given line and passes through given point.

The calculator will generate a step-by-step explanation on how to obtain the result. Improve your math knowledge with free questions in "Write an equation for a parallel or perpendicular line" and thousands of other math skills. In the last lesson, I showed you how to get the equation of a line given a point and a slope using the formula.

Anytime we need to get the equation of a line, we need two things. This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept. (For a review of how this equation is used for graphing, look at slope and graphing.). I. Find the Equation of a Line Parallel or Perpendicular to Another Line – Notes Page 3 of 4 Example 4: Find the equation of a line passing through the point (3, –4) perpendicular to the line 8x + 6y = Step 1: Find the slope of the line.

To find the slope of the given line we need to get the line into slope-intercept form (y. You must know the structure of a straight-line equation before you can write equations for parallel or perpendicular lines. The standard form of the equation is "y = mx + b," in which "m" is the slope of the line and "b" is the point where the line crosses the y-axis.
