Draw the two lines that intersect only at the point $(1,4)$. One of the lines should pass through the point $(0,-1)$. One of the lines should pass through the point $(0,-1)$. Write the equation of each of the lines you created in part (a).... In this tutorial, we learn how to determine if lines are parallel or perpendicular. You will be given two straight line equations. First, remember that parallel lines have equal slope, identical to each other. Perpendicular lines have negative reciprocal slopes. For example, 2/3 and -3/2 would be a perpendicular line. If you think of parallel lines, then you can graph them to see what they

**How do you find coordinates of a line from an equation**

Your approach was fine, in terms of finding two points that determine the first line, and two points that determine the second line. Then graphing the lines to see where they intersect. The technique I used helps to verify precisely the point at which the lines intersect.... 11/04/2013 · for my math we ae learning how to find the point of intersection, i dont want to make a graph though because they are a pain. This is grade 9 math and i just need a simple way , for example one of the questions is:: determine the point of intersections of the 2 lines.

Reflecting over that line switches the x and the y and gives you a graphical way to find the inverse without plotting tons of points. The best way to understand this concept is to see it in action. For instance, say that you know these two functions are inverses of each other: how to know if someone saves image in facebook Draw the two lines that intersect only at the point $(1,4)$. One of the lines should pass through the point $(0,-1)$. One of the lines should pass through the point $(0,-1)$. Write the equation of each of the lines you created in part (a).

## How To Know If Two Lines Intersect Without Graphing

Graphing perpendicular lines is the same as graphing any old line. In this case, the lines are presented to you in slope-intercept form . This makes it easy, at a glance, to be able to plot the y-intercept and then the slope of your line.

- Two parallel lines never intersect each other. On the other hand two lines are perpendicular when the product of their slopes is equal to -1. Two perpendicular lines intersect only once and at right angles. So when you are given two lines and asked to find if they are parallel or perpendicular lines, first compute the slope of the lines. Identify two...
- Graphing linear systems A system of linear equation comprises two or more linear equations. The solution of a linear system is the ordered pair that is a solution to all equations in the system.
- Excel's intercept function takes the data points that define a line on a graph and calculates the y value for the point on the graph where x is equal to zero. 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
