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 between two points A(x1, y1) and B(x2, y2)?

Back

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

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases, meaning the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, meaning the line falls from left to right.

Front

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot, showing the trend of the data.

Front

How do you determine the equation of a line of best fit from a scatter plot?

Back

You can determine the equation by finding two points on the line and using the slope-intercept form, or by using statistical methods like linear regression.

Front

What are consecutive odd integers?

Back

Consecutive odd integers are numbers that follow each other in the sequence of odd numbers, such as 1, 3, 5 or 11, 13, 15.

Front

How do you set up an equation for the sum of three consecutive odd integers?

Back

Let the middle integer be x. The integers can be represented as (x-2), x, and (x+2). Their sum is (x-2) + x + (x+2) = 3x.

Front

What is the process for simplifying a fraction?

Back

To simplify a fraction, divide the numerator and the denominator by their greatest common divisor (GCD).

Front

What does it mean for a fraction to be in lowest terms?

Back

A fraction is in lowest terms when the numerator and denominator have no common factors other than 1.
