Algebra I Semester Exam Review

Front

What is the equation of a linear function?

Back

A linear function is represented by an equation of the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What is a function?

Back

A function is a relation where every input (x-value) has exactly one output (y-value).

Front

How can you determine if a graph represents a function?

Back

A graph represents a function if any vertical line drawn through the graph intersects it at most once.

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x, indicating how steep the line is.

Front

What is the y-intercept of a linear function?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the equation y = mx + b.

Front

What is the difference between a function and a non-function?

Back

A function has one output for each input, while a non-function may have multiple outputs for a single input.

Front

What does the equation y = -x + 2 represent?

Back

This equation represents a linear function with a slope of -1 and a y-intercept of 2.

Front

How do you find the average from a scatterplot?

Back

To find the average from a scatterplot, identify the trend and estimate the corresponding value based on the given data points.

Front

What is a linear equation?

Back

A linear equation is an equation that forms a straight line when graphed, typically in the form y = mx + b.

Front

What is the significance of the slope in the equation y = 3x + 16?

Back

In this equation, the slope is 3, indicating that for every unit increase in x, y increases by 3 units.
