What is a scale factor?

Back

A scale factor is a number that scales, or multiplies, some quantity. In geometry, it is the ratio of the size of an object to the size of a similar object.

How do you find the scale factor of an enlargement?

Back

To find the scale factor of an enlargement, divide the length of a side of the enlarged figure by the length of the corresponding side of the original figure.

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

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x, indicating how steep the line is.

Front

What is an inequality?

Back

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

Front

How do you graph an inequality on a number line?

Back

To graph an inequality on a number line, use an open circle for < or > and a closed circle for ≤ or ≥, then shade the appropriate side.

Front

What is a solution to an inequality?

Back

A solution to an inequality is a value that makes the inequality true when substituted into the expression.

Front

What is a system of inequalities?

Back

A system of inequalities is a set of two or more inequalities with the same variables, and the solution is the region where the graphs overlap.

Front

How do you determine if a point is a solution to a system of inequalities?

Back

To determine if a point is a solution, substitute the point's coordinates into each inequality and check if all inequalities are satisfied.

Front

What does it mean for a point to be a solution to an equation?

Back

A point is a solution to an equation if its coordinates satisfy the equation when substituted.
