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

Back

The slope-intercept form is given by the equation f(x) = 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 when an equation has 'no solution'?

Back

An equation has 'no solution' when there are no values that satisfy the equation, often resulting in a contradiction.

Front

What is an identity in algebra?

Back

An identity is an equation that is true for all values of the variable, such as 0 = 0.

Front

Back

To solve, isolate x by adding 7x to both sides and then dividing by -96, remembering to flip the inequality sign.

Front

What is function notation?

Back

Function notation is a way to represent functions, typically written as f(x), where f is the function name and x is the input variable.

Back

Distribute both sides, combine like terms, and isolate x to find x = 0.83.

Front

What does it mean to round to the nearest hundredth?

Back

Rounding to the nearest hundredth means to keep two decimal places, adjusting the last digit based on the third decimal.

Back

Distribute the 2, combine like terms, and isolate x to find x = 0.
