draw a sketch base of the given imformation
Transcribed Image Text:## Mathematical Representation in ℝ³
### 1. What does the equation \( y = 8 \) represent in \( \mathbb{R}^3 \)?
- \( \quad \) \( \circ \) a point
- \( \quad \) \( \circ \) a line
- \( \quad \) \( \bullet \) a plane
- \( \quad \) \( \circ \) a circle
The equation \( y = 8 \) represents a plane in three-dimensional space \( \mathbb{R}^3 \).
### 2. What does \( z = 6 \) represent?
- \( \quad \) \( \circ \) a point
- \( \quad \) \( \circ \) a line
- \( \quad \) \( \bullet \) a plane
- \( \quad \) \( \circ \) a circle
The equation \( z = 6 \) represents a plane in three-dimensional space \( \mathbb{R}^3 \).
### 3. What does the pair of equations \( y = 8, \, z = 6 \) represent? In other words, describe the set of points \( (x, y, z) \) such that \( y = 8 \) and \( z = 6 \).
- \( \quad \) \( \circ \) a point
- \( \quad \) \( \bullet \) a line
- \( \quad \) \( \circ \) a plane
- \( \quad \) \( \circ \) a circle
The pair of equations \( y = 8 \) and \( z = 6 \) represents a line in three-dimensional space \( \mathbb{R}^3 \).
### Explanation with a Sketch
To illustrate this, one can sketch the \( \mathbb{R}^3 \) space:
- Draw the \( x \)-, \( y \)-, and \( z \)-axes.
- Show the plane \( y = 8 \) (a plane parallel to the \( xz \)-plane positioned at \( y = 8 \)).
- Show the plane \( z = 6 \) (a plane parallel to the \( xy \)-plane positioned at \( z = 6 \)).
- The intersection of these two planes will be a line along the \( x \)-axis
