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

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What does it mean for a number to be rational?

Back

A rational number can be expressed as a fraction a/b, where a and b are integers and b ≠ 0.

Front

What is the process to combine like terms in an algebraic expression?

Back

Combine like terms by adding or subtracting the coefficients of terms that have the same variable raised to the same power.

Front

How do you solve a linear equation for a variable?

Back

Isolate the variable on one side of the equation using inverse operations (addition, subtraction, multiplication, division).

Front

What is the output of the function f(x) = 2x - 5 when the input is 30?

Back

The output is f(30) = 2(30) - 5 = 60 - 5 = 55.

Front

Back

The value of x is -4.8.

Front

What is a polynomial?

Back

A polynomial is an algebraic expression that consists of variables raised to non-negative integer powers and coefficients.

Front

What is the degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the expression.

Front

What does it mean to simplify an expression?

Back

To simplify an expression means to combine like terms and reduce it to its simplest form.
