Front

In which quadrant is the point (-3, 12)?

Back

Quadrant II

Front

Evaluate f(1) if f(x) = 2x - 3.

Back

f(1) = 2

Front

What is the value of f(0) if f(x) = 2x - 2?

Back

f(0) = 4

Front

Where is point E located if E = (0, 2)?

Back

Point E is located at (0, 2).

Front

Which quadrant contains the point (2, 5)?

Back

Quadrant I

Front

Define the four quadrants in a Cartesian coordinate system.

Back

Quadrant I: (+,+), Quadrant II: (-,+), Quadrant III: (-,-), Quadrant IV: (+,-).

Front

What is the general form of a linear function?

Back

f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

How do you determine the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the y-intercept of the line represented by the equation y = 3x + 4?

Back

The y-intercept is 4.

Front

If a point lies on the x-axis, what is its y-coordinate?

Back

The y-coordinate is 0.
