Which number is a rational number?

Back

A rational number is any number that can be expressed as a fraction a/b, where a and b are integers and b is not zero. Example: 1/4 is a rational number.

What is the slope in the equation: y=4x+3?

Back

The slope of a line in the equation y=mx+b is represented by m. In this case, the slope is 4.

Front

What is the solution to the system of equations?

Back

The solution to a system of equations is the point where the equations intersect. For this system, the solution is (6, 8).

Find the distance of the segment. Round to the tenths.

Back

To find the distance between two points, use the distance formula. The distance is 9.4.

Back

Parallel lines never intersect because they have the same slopes.

Front

What is a rational number?

Back

A rational number is a number that can be expressed as a fraction of two integers.

Front

What is the formula for the slope of a line?

Back

The formula for the slope (m) between two points (x1, y1) and (x2, y2) is m = (y2 - y1) / (x2 - x1).

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

How do you find the y-intercept of a line?

Back

The y-intercept is found by setting x=0 in the equation of the line.

Front

What is the distance formula?

Back

The distance formula is d = √((x2 - x1)² + (y2 - y1)²).
