Topic 2 Test Review

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run (change in y over change in x). A positive slope indicates the line rises from left to right, while a negative slope indicates it falls.

Front

Calculate the slope of the line that passes through the points (2, 3) and (4, 7).

Back

Slope = (7 - 3) / (4 - 2) = 4 / 2 = 2.

Front

What does a slope of 1/2 mean in a real-world context?

Back

A slope of 1/2 means that for every 2 units you move horizontally, the line rises by 1 unit. This could represent a gradual incline, such as a ramp.

Front

Back

To graph this equation, identify the y-intercept (-2) and the slope (-7/4). From the y-intercept, move down 7 units and right 4 units to find another point on the line.

Front

Back

The slope is 4/5.

Front

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

Back

The slope is negative.

Front

Back

The slope is 7/4.

Front

A car travels 20 miles in 4 hours. Write the equation of the line that describes the relationship between distance and time.

Back

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates a horizontal line, meaning there is no change in y as x changes.

Front

If a line has a slope of -3, what does this indicate?

Back

This indicates that for every 1 unit increase in x, y decreases by 3 units.
