Flashcard 4.3

Front

What is the formula for calculating the slope between two points?

Back

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

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-values increase, the y-values decrease, meaning the line falls from left to right.

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

If the slope of a line is positive, what does that mean?

Back

A positive slope means that as the x-values increase, the y-values also increase, indicating the line rises from left to right.

Front

What is the first step in simplifying a fraction?

Back

The first step in simplifying a fraction is to find the greatest common divisor (GCD) of the numerator and denominator.

Back

The result is 2.

How do you determine if a slope is positive, negative, or zero from a graph?

Back

If the line rises from left to right, the slope is positive. If it falls, the slope is negative. If it is horizontal, the slope is zero.
