Front

What is the x-intercept of a function?

Back

The x-intercept is the point where the graph of a function crosses the x-axis, meaning the value of y is 0.

Front

How do you evaluate a function at a specific point, such as f(1)?

Back

To evaluate a function at a specific point, substitute the value into the function's equation and simplify to find the output.

What does the inequality -4x - 7 ≥ 21 represent?

Back

This inequality represents a range of values for x that satisfy the condition when solved.

Front

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

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

Front

What does the inequality -4x + 14 ≤ 54 mean when solved for x?

Back

This inequality shows the range of x values that make the statement true when simplified.

Front

What is the definition of a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed, typically in the form y = mx + b.

Front

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

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you graph a linear equation?

Back

To graph a linear equation, find the y-intercept, plot it on the graph, and use the slope to find another point.

Front

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal, while an inequality shows a relationship where one expression is greater than or less than another.

Front

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

Back

A function is increasing if its output values rise as the input values increase, and decreasing if the output values fall as the input values increase.
