## How do you find the intersection of two lines vectors?

For two lines to intersect, each of the three components of the two position vectors at the point of intersection must be equal. Therefore we can set up 3 simultaneous equations, one for each component. and we solve these in the usual way to find our s and t, showing our working.

## How do you determine if a line intersects another line?

They intersect if their intersection point lies within the darker middle rectangle (i.e. the area in space that they both occupy). In other words, if the intersection point is (x,y), then x must be less than the smallest right-side value (the x-coordinate of AH here), and larger than the smallest left-side value (GB).

**Which statement about the conditional statement if two lines intersect then their intersection is a point is true?**

If a conditional and its converse are both true, we can write it as a Biconditional using if and only if. Biconditional Two lines intersect iff their intersection is exactly one point. Conditional If two lines intersect, then the intersection is one point. Converse If two lines contain one point, then they intersect.

**How do you determine if an equation is intersecting?**

To find the intersection of two lines, you first need the equation for each line. At the intersection, x x x and y y y have the same value for each equation. This means that the equations are equal to each other. We can therefore solve for x x x.

### How do you know if an equation is intersecting?

We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.

### What kind of statement is this if two lines intersect then their intersection is exactly one point?

Postulate

Postulate: If two planes intersect, then their intersection is a line. The point Q lies on line m and line l. Postulate: If two lines intersect, then their intersection is exactly one point. a) The intersecon of two planes contains at least two points.

**What kind of statement is if two lines intersect then their intersection is a point?**

Conditional If two lines intersect, then the intersection is one point.

**How do you find the intersection on a TI 83 Plus?**

The TI-83 will show you the equation being graphed in the upper left hand corner of the screen. For the First Curve, hit enter. For the Guess, arrow to the intersection and press enter. The TI-83 will return a value for x and y.
