Semester 1 Algebra 1 Vocabulary Review

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases, resulting in an upward slant from left to right.

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 slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is zero.

Front

What is a function?

Back

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

Front

How can you determine if a relation is a function using the vertical line test?

Back

If a vertical line intersects the graph at more than one point, the relation is not a function.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x) for which the function is defined.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y) that the function can produce.

Front

How do you find the y-intercept of a line?

Back

The y-intercept is found by setting x = 0 in the equation of the line and solving for y.
