Algebra 1 - Chapter 4 Review

Front

What does it mean for two quantities to be proportional?

Back

Two quantities are proportional if they maintain a constant ratio or relationship to each other.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise over run).

Front

How do you find the slope from an equation in slope-intercept form?

Back

Front

What is the y-intercept of an equation?

Back

Front

What does the notation h(4) = 5 mean in a function?

Back

It means that after 4 weeks, the height of the plant is 5 inches.

Front

How do you determine if a relationship is linear?

Back

A relationship is linear if it can be represented by a straight line on a graph, meaning it has a constant slope.

Front

What is the formula for calculating slope between two points (x1, y1) and (x2, y2)?

Back

Front

What is the significance of a slope of 0?

Back

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

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant from left to right.

Front

What is the relationship between slope and steepness?

Back

A larger absolute value of the slope indicates a steeper line, while a smaller absolute value indicates a gentler slope.
