What this Writing and Graphing Linear Functions in Three Forms quiz checks
- Slope = (y₂ − y₁) ÷ (x₂ − x₁) for any two points on the line.
- In y = mx + b, m is the slope and b is the y-intercept.
- Point-slope form needs one point and the slope.
- Parallel lines have equal slopes; perpendicular slopes multiply to −1.
- In a model, the rate of change is the slope and the starting value is the y-intercept.
The 10 questions of the quiz
- What is the slope of the line through (3, −7) and (9, 17)?
- What is the y-intercept of y = 7x − 9?
- Which equation matches the graph?
- Which is point-slope form for the slope −3 through (2, 5)?
- Which is standard form of y = 3x − 4?
- What slope does a line parallel to y = 4x + 1 have?
- What slope does a line perpendicular to y = 23x have?
- What is the slope of the graphed line?
- Each option lists four ordered pairs with consecutive x-values. Which option is a linear function?
- A line has slope 3 and passes through (2, 7). What is its y-intercept?
