At the point of intersecting lines, the points are equal.

Watch this:

The equation of the 1st line is Y=3x-7

The equation of the 2nd line is Y=-2x+3

Remember, at the intersecting points they are equal. So then:

3x-7=-2x+3 Now solve for x (get x by itself in the form of x=whatever)

3x-7=-2x+3

+2x +2x (What you do to one side of the equal sign you must do to the other)

____________

5x -7 = 3

+7 = +7

____________

5x = 10 now divide by 5 to remove the 5 from the x in 5x.

___ ___

5 5

x=2

Then you sub x=2 into any of the two equation. Lets use the first one:

Y=3x-7 becomes Y=3(2)-7

Y=6-7

Y=-1

So the intersecting point is (2,-1)

The difference between interior lines and exterior lines are thatInterior lines: Are the lines that are in the inside of the shape or whatever you are trying to find the interior of.Exterior Lines: Are the lines that are outside of the shape or whatever you are trying to find the exterior of.

If the equations are in y= form, set the two equations equal to each other. Then solve for x. The x value that you get is the x coordinate of the intersection point. To find the y coordinate of the intersection point, plug the x you just got into either equation and simplify so that y= some number. There are other methods of solving a system of equations: matrices, substitution, elimination, and graphing, but the above method is my favorite!

In simple terms, if you draw lines from each corner/vertex, to the middle of the opposite side, you will find the lines converge or meet at one point. That point is the centroid.

to find the altitude of a triangle you connect each vertex perpendicularly to the opposite segment all three points will meet at one point known as the orthocenter -9th grader

Graph the two lines or equations you want to find the intersection of. Then adjust the window so that you can see the intersection point. (If you don't know where it is, try pressing ZOOM and choosing ZoomFit.) Then press 2ND CALC (above TRACE) and choose option 5, intersect. Use the up and down arrows to select the first equation you want to find the intersection point on, and press ENTER. Do the same thing for the second equation. The calculator will now say "Guess?". Use the left and right arrows to move the x-like shape as close to the intersection point as possible, then press ENTER. The calculator will tell you the intersection point and the bottom of the screen. If you get a NO SIGN CHNG error, then it might be because the intersection point is not on the screen. Change the window so that you can see the intersection point and try again. Also, make sure that your guess is somewhat close to the intersection point.

You must first write an equation for the line through the point perpendicular to the line. Then, find the intersection between the two lines. Lastly, use this point and the distance formula to find the length of the perpendicular segment connecting the given point and the original line. That will lead to the following formula, d = |AX1+BY1- C|/(sqrt(A2+B2)), Where A, B and C represent the coefficients of the given line in standard form and (X1,Y1) is the given point.

Yes, an Octagon does have a center point. The easiest way for me to find this is by drawing lines between opposite vertexes. You should end up with four lines and they should be crossing at one point. That is your center point! :V

The step to verify an isosceles triangle is: 1) Find the intersection points of the lines. 2) Find the distance for each intersection points. 3) If 2 of the distance are the same then it is an isosceles triangle.

Using the point of intersection gives a more accurate mole ratio because it represents the stoichiometric ratio of the reactants based on the balanced chemical equation. In contrast, the trial with the greatest volume of precipitate may be influenced by factors such as experimental error or impurities, leading to a less precise ratio.
