Front

What is the x-intercept of a linear equation?

Back

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

Front

How do you write a linear inequality in standard form?

Back

A linear inequality in standard form is written as Ax + By < C, Ax + By ≤ C, Ax + By > C, or Ax + By ≥ C, where A, B, and C are constants.

Front

What does it mean for a relationship to be directly proportional?

Back

A relationship is directly proportional if one quantity increases or decreases at a constant rate with respect to another quantity.

Front

How do you calculate the total earnings based on hours worked and hourly rate?

Back

Total earnings = Hourly rate × Number of hours worked.

Front

What is the standard form of a linear equation?

Back

The standard form of a linear equation is Ax + By = C, where A, B, and C are integers and A is non-negative.

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 find the slope between two points?

Back

The slope (m) between two points (x1, y1) and (x2, y2) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What is the meaning of the term 'inequality' in mathematics?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, or not equal to the other.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, indicating the value of y when x is 0.

Front

How do you graph a linear inequality?

Back

To graph a linear inequality, first graph the corresponding equation as a line, then shade the region that satisfies the inequality.
