1st Semester Algebra Review

Front

Solve for x: 52 = -5x - 3

Back

x = -11

Front

What is the y-intercept in the equation x + 2y = 4?

Back

2

Front

What is the definition of a function?

Back

Every input has only ONE output.

Front

What is the first step to solve this equation: 11 - 3x = 44?

Back

Subtract 11 from both sides.

Front

Is this graph a function or not a function? (Graph not shown)

Back

Function

Front

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

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does it mean for two lines to be parallel?

Back

They have the same slope and will never intersect.

Front

What is the quadratic formula?

Back

x = (-b ± √(b² - 4ac)) / 2a.

Front

What is the domain of a function?

Back

The set of all possible input values (x-values).
