Slope-Tables&Graphs(1.3.25)

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is zero.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-value increases, the y-value also increases.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-value increases, the y-value decreases.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the slope of the line represented by the points (1, 2) and (3, 6)?

Back

The slope is (6 - 2) / (3 - 1) = 4 / 2 = 2.

Front

What is the slope of the line represented by the points (2, 3) and (5, 1)?

Back

The slope is (1 - 3) / (5 - 2) = -2 / 3.

Front

What does a slope of 1 mean?

Back

A slope of 1 means that for every unit increase in x, y increases by the same amount.

Front

What is the slope of a line that goes down from left to right?

Back

The slope is negative.

Front

If a line has a slope of 3, what does this mean in terms of rise over run?

Back

It means that for every 1 unit you move to the right (run), the line rises 3 units (rise).
