Algebra 1 Semester Exam Mixed Review

Front

What is the relationship between the lines y = 2x + 4 and y = 2x - 7?

Back

The lines are parallel because they have the same slope (2) and different y-intercepts.

Front

Simplify the expression: 2x - 4 + 5x + 1

Back

The simplified expression is 7x - 3.

Front

Solve for x: x + 2 = 12

Back

x = 10.

Front

Evaluate f(8) for the function f(x) = 3x - 2

Back

f(8) = 22.

Front

What is the x-intercept of the line represented by the equation y = 2x - 12?

Back

The x-intercept is (6,0).

Front

What is the slope of the line represented by the equation y = 3x + 1?

Back

The slope is 3.

Front

What is the y-intercept of the line represented by the equation y = -4x + 5?

Back

The y-intercept is (0, 5).

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

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.

Front

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

The slope m is calculated as m = (y2 - y1) / (x2 - x1).
