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 parallel to another line?

Back

The slope of a line parallel to another line is the same as the slope of the original line.

Front

What is a box-and-whisker plot?

Back

A box-and-whisker plot is a graphical representation of a dataset that shows its minimum, first quartile, median, third quartile, and maximum.

Front

How do you calculate the range of a dataset?

Back

The range is calculated by subtracting the smallest value from the largest value in the dataset.

Front

What is the interquartile range (IQR)?

Back

The interquartile range (IQR) is the difference between the first quartile (Q1) and the third quartile (Q3) in a dataset.

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 is the rule for dividing exponents with the same base?

Back

Front

What is the formula for finding the median in a dataset?

Back

To find the median, arrange the data in ascending order and locate the middle value. If there is an even number of values, average the two middle values.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x = 0.

Front

How do you interpret the quartiles in a box-and-whisker plot?

Back

The first quartile (Q1) is the median of the lower half of the data, the third quartile (Q3) is the median of the upper half, and the median (Q2) divides the dataset into two equal parts.
