Part 1 Review Test: Algebra II S1 Finals (2024 - 2025)

Front

What is the elimination method in solving systems of equations?

Back

The elimination method involves adding or subtracting equations to eliminate one variable, making it easier to solve for the other variable.

Front

How do you find the slope of a line given two points?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect, regardless of how far they are extended.

Front

What is the range of a set of ordered pairs?

Back

The range is the set of all second elements (y-values) from the ordered pairs.

Front

How do you evaluate a function at a specific point?

Back

To evaluate a function f(x) at a point x = a, substitute 'a' into the function and simplify.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables that are solved together.

Front

What does it mean for a line to have an undefined slope?

Back

A line has an undefined slope if it is vertical, meaning it goes straight up and down, and does not have a defined rise over run.

Front

What is the difference between intersecting lines and parallel lines?

Back

Intersecting lines cross each other at one point, while parallel lines never meet.

Front

How can you determine if a function is linear?

Back

A function is linear if it can be represented by a straight line on a graph, which means it has the form f(x) = mx + b.

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.
