Flashcard 1: What effect does a positive slope have on a slope field?

Answer: Lines tilt upward from left to right. Positive slope creates upward-slanting segments.

Flashcard 2: How do you determine equilibrium solutions from a slope field?

Answer: Look for horizontal line segments. Zero slope indicates equilibrium solutions.

Flashcard 3: What is the slope at $(2, 0)$ for $dy/dx = \frac{1}{y}$ ?

Answer: Slope is undefined. Division by zero creates undefined slope.

Flashcard 4: What effect does a positive slope have on a slope field?

Answer: Lines tilt upward from left to right. Positive slope creates upward-slanting segments.

Flashcard 5: How is a slope field constructed for $dy/dx = x + y$ ?

Answer: Compute slopes at grid points using $m = x + y$ . Substitute coordinates into the differential equation.

Flashcard 6: What information can you obtain from a slope field?

Answer: The general shape and behavior of solution curves. Reveals overall patterns and equilibrium points.

Flashcard 7: How is $dy/dx = 0$ represented in a slope field?

Answer: Horizontal line segments. Zero slope creates flat line segments.

Flashcard 8: What does a horizontal line segment in a slope field indicate?

Answer: The slope is zero at that point. Zero slope means no vertical change.

Flashcard 9: What effect does a negative slope have on a slope field?

Answer: Lines tilt downward from left to right. Negative slope creates downward-slanting segments.

Flashcard 10: Which direction do lines in a slope field point for $dy/dx = -1$ ?

Answer: Lines point downward at 45 degrees. Constant negative slope creates uniform downward tilt.

Flashcard 11: How do you find the slope at $(x, y)$ for $dy/dx = x^2 + y^2$ ?

Answer: Compute $x^2 + y^2$ at $(x, y)$ . Evaluate the expression at each grid point.

Flashcard 12: How do you determine equilibrium solutions from a slope field?

Answer: Look for horizontal line segments. Zero slope indicates equilibrium solutions.

Flashcard 13: Which direction do lines in a slope field point for $dy/dx = -1$ ?

Answer: Lines point downward at 45 degrees. Constant negative slope creates uniform downward tilt.

Flashcard 14: How is $dy/dx = 0$ represented in a slope field?

Answer: Horizontal line segments. Zero slope creates flat line segments.

Flashcard 15: What is the slope at $(0, 1)$ for $dy/dx = \frac{1}{x}$ ?

Answer: Slope is undefined. Division by zero creates undefined slope.

Flashcard 16: How do you sketch a slope field for $dy/dx = y$ ?

Answer: Compute $m = y$ at grid points. Evaluate $y$ at each grid point for slope.

Flashcard 17: What does a vertical line segment in a slope field indicate?

Answer: The slope approaches infinity. Infinite slope means vertical tangent line.

Flashcard 18: What does it mean for a slope field to have symmetry?

Answer: The slope pattern repeats across an axis. Pattern mirrors across coordinate axes.

Flashcard 19: How is a slope field constructed for $dy/dx = x + y$ ?

Answer: Compute slopes at grid points using $m = x + y$ . Substitute coordinates into the differential equation.

Flashcard 20: What does each line segment in a slope field represent?

Answer: The slope of the solution curve at a given point. Each segment shows the tangent direction at that point.

Flashcard 21: How do you find the slope at $(x, y)$ for $dy/dx = x^2 + y^2$ ?

Answer: Compute $x^2 + y^2$ at $(x, y)$ . Evaluate the expression at each grid point.

Flashcard 22: What is a key feature of slope fields for $dy/dx = y/x$ ?

Answer: Lines are radial from the origin. Lines point away from origin along rays.

Flashcard 23: What is the slope at $(0, 1)$ for $dy/dx = \frac{1}{x}$ ?

Answer: Slope is undefined. Division by zero creates undefined slope.
