What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor that multiplies a variable in an algebraic expression. For example, in the expression 4n, 4 is the coefficient of n.

Front

How do you identify the coefficient of a term in an expression?

Back

To identify the coefficient of a term, look for the number that is multiplied by the variable. For example, in the term -2n^2, -2 is the coefficient.

Front

What is the standard form of a linear function?

Back

The standard form of a linear function is expressed as f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the intersection point of two linear equations?

Back

To find the intersection point, solve the equations simultaneously to find the values of x and y that satisfy both equations.

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 does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1, meaning they intersect at a right angle.

Front

What is the distributive property in algebra?

Back

The distributive property states that a(b + c) = ab + ac, meaning you can distribute a factor across a sum.

Front

How do you multiply two binomials?

Back

To multiply two binomials, use the distributive property (FOIL method): First, Outer, Inner, Last.

Front

What is a function in mathematics?

Back

A function is a relation that assigns exactly one output for each input. It can be represented as f(x).

Front

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

Back

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