In summary, the problem is to determine the relationship between a given plane and line. The line is defined by a vector equation and the plane is defined by a normal vector. To be perpendicular, the normal vector of the plane must be perpendicular to the direction vector of the line. To be parallel, the normal vector and direction vector must be parallel. The solution must be found by analyzing these conditions.

Homework Statement



Determin if the plan given by (-x+2z=10) and the line given by r=<5,2-t,10+4t> are othogonal,parllel or neither??

What is the solution?

I'm not going to give you the solution- the point is for you to find the solution. I will suggest this: your line is given by the vector equation r= <5, 2, 10>+ t<0,-1,4> so <0, -1, 4> is a vector pointing in the direction of that line. Also, the plane -x+ 0y+ 2z= 10 has <-1, 0, 2> as normal vector (that is <-1, 0, 2> is perpendicular to the plane).

What must be true of those two vectors in order that the line and plane be perpendicular? parallel? Are those true?
 

1. Are Pln and Line orthogonal or parallel?

The answer is that it depends on the values of x and z in the given equation. If x and z are both equal to 0, then Pln and Line are parallel. If x and z are not equal to 0, then Pln and Line are neither parallel nor orthogonal.

2. How do I determine if two lines are orthogonal or parallel?

To determine if two lines are orthogonal, you can use the dot product formula. If the dot product of the two lines is equal to 0, then the lines are orthogonal. To determine if two lines are parallel, you can compare the slopes of the two lines. If the slopes are equal, then the lines are parallel.

3. Can Pln and Line be both orthogonal and parallel?

No, Pln and Line cannot be both orthogonal and parallel. If two lines are orthogonal, they intersect at a 90 degree angle. If two lines are parallel, they never intersect. Therefore, they cannot be both orthogonal and parallel.

4. How can I find the equation of a line that is parallel to Pln and passes through a given point?

To find the equation of a line that is parallel to Pln, you can use the slope-intercept form of a line (y=mx+b) and substitute the slope of Pln for m. Then, you can plug in the coordinates of the given point for x and y to solve for b. This will give you the equation of the parallel line.

5. Is there a visual way to determine if two lines are orthogonal or parallel?

Yes, you can use a graph to determine if two lines are orthogonal or parallel. If the lines are orthogonal, they will intersect at a 90 degree angle. If the lines are parallel, they will never intersect and will have the same slope. You can also use a protractor to measure the angle between the lines to determine if they are orthogonal.
