Front

What is the formula to calculate the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

What is the slope of the line that passes through the points (-1,10) and (5,2)?

Back

The slope is -4/3.

Front

What is the definition of a function?

Back

A function is a relation that assigns exactly one output for each input.

Front

What is the value of g(3) if g(1)=3 and g(n)=4g(n-1)+2?

Back

g(3) = 26.

Front

What is the range of an absolute value function?

Back

The range of an absolute value function is [0, ∞) if the vertex is at the origin.

Front

What is the general form of a linear inequality?

Back

A linear inequality can be expressed as ax + by < c, ax + by ≤ c, ax + by > c, or ax + by ≥ c.

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.

Front

How do you find the y-intercept of the equation -7x - 3y = 21?

Back

To find the y-intercept, set x = 0. The y-intercept is -7.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input has exactly one output.

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex represents the maximum or minimum point of the parabola.
