ViewLinear Functions and Graphing Mastery
This quiz tests your understanding of linear functions in the form f(x) = mx + b, graphing techniques, and interpreting slope and y-intercept.
Key concepts:
- Slope-intercept form y = mx + b
- Identifying slope and y-intercept from equations and graphs
- Graphing linear equations
- Finding equations from graphs
- Parallel and perpendicular lines
Remember: The slope m represents rate of change, and b is where the line crosses the y-axis!
Terms and Core Concepts (5)
Slope-Intercept Form
Linear equation written as y = mx + b.
Slope (m)
Rate of change, calculated as rise/run.
Y-Intercept (b)
Point where line crosses y-axis, at (0, b).
Parallel Lines
Lines with same slope but different y-intercepts.
Perpendicular Lines
Lines whose slopes are negative reciprocals.
Frequently Asked Questions (FAQ)
Use the formula m = (y₂-y₁)/(x₂-x₁). Subtract y-coordinates and divide by subtraction of x-coordinates.
Vertical lines have undefined slope because you'd divide by zero. They're written as x = constant.
Multiply their slopes. If the product is -1, they're perpendicular.
