How do you find the point of intersection between two lines?
At the point of intersecting lines, the points are equal.
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)
+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.
Then you sub x=2 into any of the two equation. Lets use the first one:
Y=3x-7 becomes Y=3(2)-7
So the intersecting point is (2,-1)
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…
Why is it more accurate to use the point of intersection of the two lines to find the mole ratio rather than the ratio associated with the trial with the greatest volume of precipitate?
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…
Grid references are points defined by the coordinates of a grid or map system. The reference numbers can be used to denote a particular point or area on the grid. Most maps are labeled with numbers or letters on horizontal and vertical lines to allow you to find a given point (the intersection of those lines). Geographic maps may use latitude and longitude.
How do you determine given two lines which share a plane the point on each line where the shortest distance between the two lines is equal to some quantity?
If the two lines are parallel, then the shortest distance between them is a single, fixed quantity. It is the distance between any point on one line along the perpendicular to the line. Now consider the situation where the two lines meet at a point X, at an angle 2y degrees. Suppose you wish to find points on the lines such that the shortest distance between them is 2d units. [The reason for using multiples…
where the two lines cross is called their point of intersection Here we will cover a method for finding the point of intersection for two linear functions. That is, we will find the (x, y) coordinate pair for the point were two lines cross. Our example will use these two functions: f(x) = 2x + 3 g(x) = -0.5x + 7 We will call the first one Line 1, and the second Line 2. Since…
Join any pointof the image(a vertex is ideal) to the corresponding point of the pre-image by a straight line. Repeat for another point. These two lines will intersect at the centre of enlargement. As a check, repeat for a third pair of points: if the third line does not go through the point of intersection of the first two, you have made a mistake.
