Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form of a linear equation is given by the formula y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the x-intercept of a linear equation?

Back

To find the x-intercept of a linear equation, set y = 0 and solve for x.

Front

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

Back

The y-intercept represents the point where the graph of the function crosses the y-axis, indicating the value of y when x = 0.

Front

What is a parent function in algebra?

Back

A parent function is the simplest form of a function in a family of functions, which retains the essential characteristics of that family.

Front

How do you determine the slope of a line given two points?

Back

The slope (m) of a line given two points (x1, y1) and (x2, y2) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the steepness of the line and the direction of the relationship between the variables; a positive slope means the line rises, while a negative slope means it falls.

Front

What is the relationship between the x-intercept and y-intercept in a linear function?

Back

The x-intercept and y-intercept are the points where the graph intersects the x-axis and y-axis, respectively, and they can be used to graph the linear function.

Front

How can you identify a linear function from its graph?

Back

A linear function can be identified by a straight line on the graph, indicating a constant rate of change.

Front

What does it mean for a function to be increasing or decreasing?

Back

A function is increasing if its graph rises as you move from left to right, and decreasing if it falls as you move from left to right.

Front

What is the formula for finding the distance between two points in a coordinate plane?

Back

The distance (d) between two points (x1, y1) and (x2, y2) is given by the formula d = √((x2 - x1)² + (y2 - y1)²).
