What is a linear regression equation?

Back

A linear regression equation is a mathematical representation of the relationship between two variables, typically in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you calculate the slope in a linear regression?

Back

The slope (m) in a linear regression is calculated by taking the change in the y-values divided by the change in the x-values between two points on the line.

Front

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

Back

The y-intercept (b) represents the value of y when x is 0, indicating where the line crosses the y-axis.

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions, showing that one is less than, greater than, less than or equal to, or greater than or equal to the other.

Front

What does the symbol '>' mean in an inequality?

Back

'>' means 'greater than', indicating that the value on the left side is larger than the value on the right side.

Front

How do you solve a linear inequality?

Back

To solve a linear inequality, isolate the variable on one side of the inequality sign, similar to solving an equation, while remembering to reverse the inequality sign if you multiply or divide by a negative number.

Front

What is a solution set?

Back

A solution set is the set of all values that satisfy a given mathematical statement or inequality.

Front

What does it mean if a solution is 'greater than or equal to'?

Back

'Greater than or equal to' means that the value can be either greater than or exactly equal to the specified number.

Front

How do you graph a linear inequality?

Back

To graph a linear inequality, first graph the corresponding linear equation as a solid line (for '≥' or '≤') or a dashed line (for '>' or '<'), then shade the region that satisfies the inequality.

What is the first step in solving the inequality -4x + 10 ≥ 5x + 55?

Back

The first step is to isolate the variable x by moving all terms involving x to one side and constant terms to the other side.
