What is the formula for the perimeter of a triangle?

Back

The perimeter of a triangle is the sum of the lengths of its sides: P = a + b + c.

Front

How do you evaluate a function at a specific point?

Back

To evaluate a function h(x) at a point x = a, substitute a into the function: h(a).

Front

What is a solution to a system of inequalities?

Back

A solution to a system of inequalities is a set of values that satisfies all inequalities in the system.

Front

What is a linear function?

Back

A linear function is a function that can be graphically represented as a straight line, typically in the form y = mx + b.

Front

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

Back

Substitute the point into each inequality; if it satisfies all, it is a solution.

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

What does it mean for a function to be linear?

Back

A function is linear if it has a constant rate of change, represented by a straight line on a graph.

Front

How do you find the y-intercept of a linear function?

Back

Set x = 0 in the equation of the line and solve for y.

Front

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

Back

The slope indicates the steepness of the line and the direction of the relationship between x and y.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input has exactly one output.
