Algebra 1 SOL Review #1

Front

What is a function?

Back

A relation where each input has exactly one output.

Front

How do you identify a function from a set of relations?

Back

Use the vertical line test; if a vertical line intersects the graph at more than one point, it is not a function.

Front

Translate the expression: One fourth times the cube root of x less five.

Back

(1/4) * (x^(1/3)) - 5.

Front

What is the solution to the system of equations: x + 2y = 23 and 4x - y = -7?

Back

(1, 11).

Front

Simplify √28.

Back

2√7.

Front

What is the equation for the ordered pairs (-3, -14), (-1, -4), (0, 1), (2, 11), (5, 26)?

Back

y = 5x + 1.

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

What does the term 'slope' refer to in a linear equation?

Back

The rate of change of y with respect to x; it indicates the steepness of the line.

Front

How do you find the y-intercept of a linear equation?

Back

Set x = 0 in the equation and solve for y.

Front

What is the difference between a linear function and a non-linear function?

Back

A linear function graphs to a straight line, while a non-linear function graphs to a curve.
