Algebra 1 Semester 1 final exam review

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It is represented as (0, b) where b is the value of y when x = 0.

Solve for x: 2x - 3 + 4x = 27

Back

Front

Name the x- and y-intercepts for the equation: 2x + y = 6

Back

The x-intercept is (3, 0) and the y-intercept is (0, 6).

Front

Is this table a function or not a function?

Back

Not a Function: A relation is not a function if any x-value is paired with more than one y-value.

Give the x-intercept for the equation: 3x + 8y = 24

Back

The x-intercept is (8, 0).

Front

What does it mean for a graph to be linear?

Back

A linear graph is a straight line that represents a linear equation, showing a constant rate of change.

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers, and A should be non-negative.

Front

How do 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.
