Algebra 1 First Semester Exam Review 2024

Front

Does the table represent a function?

Back

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

Front

Which graph best represents the inequality?

Back

To determine the correct graph for an inequality, identify the boundary line and whether the region above or below the line satisfies the inequality.

Front

What is the first step to solve this equation: x - 5 = 7 - 2x?

Back

Add 2x to both sides of the equation to combine like terms.

Front

Which operation will you use to solve a = b + c for c?

Back

Subtract b from both sides of the equation to isolate c.

Front

Rewrite the equation 6x - 2y = 10 in slope-intercept form.

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. The equation can be rewritten as y = 3x - 5.

Front

What is the slope of the line represented by the equation y = 2x + 3?

Back

The slope (m) is the coefficient of x, which is 2.

Front

How do you find the x-intercept of the equation 3x + 4y = 12?

Back

Set y = 0 and solve for x. The x-intercept is (4, 0).

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.

Front

What is the quadratic formula used to solve ax^2 + bx + c = 0?

Back

The quadratic formula is x = (-b ± √(b² - 4ac)) / (2a).

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables.
