What is the y-intercept of a linear function?

Back

The y-intercept is the point where the graph of the function crosses the y-axis, represented as (0, b) where b is the value of the function when x=0.

Front

What is a system of inequalities?

Back

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

How do you determine if a triangle is a right triangle using coordinates?

Back

Use the Pythagorean theorem: if the square of the length of the longest side equals the sum of the squares of the other two sides, the triangle is a right triangle.

Front

What is the significance of the x-intercept?

Back

The x-intercept is the point where the graph crosses the x-axis, represented as (a, 0) where a is the value of the function when y=0.

Front

How do you solve a system of inequalities graphically?

Back

Graph each inequality on the same coordinate plane and identify the overlapping region, which represents the solution set.

Front

What is the product of a rational number and an irrational number?

Back

The product of a rational number and an irrational number is always irrational.
