Chapter 4 Review for Test

Front

What is the definition of slope in a graph?

Back

Slope is a measure of the steepness or incline of a line, calculated as the ratio of the vertical change to the horizontal change between two points on the line.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical, meaning it goes straight up and down and does not have a defined angle.

Front

What does a slope of zero indicate about a line?

Back

A slope of zero indicates that the line is horizontal, meaning it does not rise or fall as it moves along the x-axis.

Front

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

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

What is the slope of the line that passes through the points (4, -3) and (8, -3)?

Back

The slope is 0, as the y-coordinates are the same, indicating a horizontal line.

Front

Back

The slope is 0, as this is a horizontal line at y = -2.

Front

What is the slope of a line that rises 3 units for every 2 units it runs?

Back

Front

Write the equation of a line with slope 4 that passes through the point (-2, 5).

Back

Front

What is the slope of a line that falls as it moves from left to right?

Back

The slope is negative.

Front

If a line has a slope of 2, what does this mean in terms of rise and run?

Back

For every 2 units the line rises, it runs 1 unit horizontally.
