SUMMARY

The discussion focuses on finding the equation of a plane defined by the line in the xy-plane where y = 1 and the line in the xz-plane where z = 2. The equation of the plane can be expressed in the form Ax + By + Cz = D. The slope of the plane, calculated as Δz/Δy, is determined to be 2, leading to the conclusion that the equation can be simplified to z = 2 - 2y. This solution clarifies the relationship between the lines and the plane in question.

PREREQUISITES
  • Understanding of linear equations in three dimensions (Ax + By + Cz = D)
  • Familiarity with graphing planes and lines in 3D space
  • Knowledge of slope calculations in the context of plane equations
  • Experience with mathematical software tools like Cramster for problem-solving
NEXT STEPS
  • Study the derivation of plane equations from line equations in 3D geometry
  • Learn about the implications of slope in three-dimensional space
  • Explore the use of mathematical software for visualizing planes and lines
  • Investigate additional examples of plane equations in calculus and linear algebra
USEFUL FOR

Students studying calculus, particularly those tackling multivariable functions and plane equations, as well as educators looking for examples to illustrate these concepts.

Homework Statement


Find an equation for the plane containing the line in the xy-plane where y = 1, and the line in the xz-plane where z = 2


Homework Equations


Ax+By+C= f(x,y) or (z)


The Attempt at a Solution


Ok so i started off by graphing and i see when x and y are 0 z = 2 and when z and x are x
y = 1
So i know that to find the slope n (Δz/Δy) = 2/1 = 2

After this I am lost as what to do. I use cramster, but the explanation is poor and
says Ax+By+Cz = 1, but I don't see how this equation is related.

What line in the yz-plane is is also in the plane whose equation you are looking for?
 
z = 2 -2y?

Correct !
 
Thanks for the help. Much appreciated. This one was bothering me for a while.
