What is the solution to the equation 2x + 3 = 9?

Back

x = 3

Front

Define a linear equation.

Back

An equation that makes a straight line when graphed, typically in the form y = mx + b.

Front

What is the slope of the line represented by the equation y = 2x + 1?

Back

The slope is 2.

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 does the term 'domain' refer to in a function?

Back

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

Front

What is the range of the function f(x) = x^2?

Back

The range is all non-negative real numbers, [0, ∞).

Front

Solve for y: 3y - 6 = 0.

Back

y = 2.

Front

What is the difference between independent and dependent variables?

Back

Independent variables are manipulated, while dependent variables are measured.

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are integers.

Front

What does it mean for two lines to be parallel?

Back

They have the same slope and will never intersect.
