# Write an equation of a parallel or perpendicular line

OK, now we have our slope, which is 4. Let's add 3 to both sides of this equation, so if we add 3 to both sides-- I just want to get rid of this 3 right here-- what do we get.

What is the slope of a vertical line. Since the slopes of perpendicular lines are negative reciprocals of each other, what do you think the slope of any perpendicular line to this line is. Then the rod will be balanced, no force will be exerted on the pivot, and the sum of all of the clockwise moments from the particles of the rod will be equal to the counterclockwise moment Fd produced by force F where d is the distance from the pivot to the center of gravity, as shown in the figure.

The above form is called the slope intercept form of a line. If you said undefined, you are right on. And we can actually use the point slope form right here. In developing the ideas for computing the location of the center of gravity we will view a body as an assemblage of individual particles.

A line is parallel to another if their slopes are identical. A number between 0 and 1 used to quantify likelihood for processes that have uncertain outcomes such as tossing a coin, selecting a person at random from a group of people, tossing a ball at a target, or testing for a medical condition.

Rigid motions are here assumed to preserve distances and angle measures. For a data set with median M, the first quartile is the median of the data values less than M. The center of gravity is the same as the center of mass since weight and mass are proportional. Since parallel lines have the same slope what do you think the slope of the parallel line is going to be.

Then the rod will be balanced, no force will be exerted on the pivot, and the sum of all of the clockwise moments from the particles of the rod will be equal to the counterclockwise moment Fd produced by force F where d is the distance from the pivot to the center of gravity, as shown in the figure.

Perpendicular lines cross each other at a degree angle. If the pivot is directly below the center of gravity, the rod is balanced, and the sum of all the clockwise moments from particles to the right of the pivot is equal to the sum of all the counterclockwise moments from the particles to the left of the pivot.

For example, for any two distinct points, there is a unique line containing them, and any two distinct lines intersect in at most one point. We need to do a little digging to get our slope. Suppose the weights of the masses are w1, w2, w3, The median of a list of values is the value appearing at the center of a sorted version of the list—or the mean of the two central values, if the list contains an even number of values.

Find the slope of a line passing through the points 23 and 0-1 -24 and -26 52 and -72 Solution to Example1: A study of Euler angles will help understand three-dimensional transformations. Find the slope of the line that is a parallel and b perpendicular to the line. Find the slope of a line passing through the points -27 and -2-1 24 and -26 -1-2 and 4-2 Example 2: Thus if we were able to compute the clockwise moments of the particles of the rod with respect to the pivot point and knew the weight of the rod, we would then be able to compute the distance d from the pivot to the center of gravity.

Let me do it in a better color. The law of the lever states that in order to have equilibrium the sum of the counterclockwise torques or moments must be equal to the sum of the clockwise torques. Both sets of lines are important for many geometric proofs, so it is important to recognize them graphically and algebraically.

Slope of the perpendicular line: The two terms are synonymous. kcc1 Count to by ones and by tens. kcc2 Count forward beginning from a given number within the known sequence (instead of having to begin at 1).

kcc3 Write numbers from 0 to Represent a number of objects with a written numeral (with 0 representing a count of no objects). kcc4a When counting objects, say the number names in the standard order, pairing each object with one and only.
