Baker Math 1 EOC Review Activity 1

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, typically represented by the letter 'm' in the equation of a line (y = mx + b). It is calculated as the change in y divided by the change in x (rise/run).

Front

How do you calculate the standard deviation of a data set?

Back

Standard deviation is calculated by taking the square root of the variance, which is the average of the squared differences from the mean.

Front

What does the function f(x) = 0.35x + 22 represent in a real-world context?

Back

This function represents the total cost (f(x)) of chocolate after paying a membership fee of $22 and $0.35 per ounce of chocolate.

Front

What is the first step to solve the equation 11 - 3x = 44?

Back

The first step is to subtract 11 from both sides to isolate the term with x.

Front

In the equation y = mx + b, what does 'm' represent?

Back

'm' represents the slope of the line.

Front

What is the formula for calculating the slope between two points (x1, y1) and (x2, y2)?

Back

The formula is m = (y2 - y1) / (x2 - x1).

Front

What is the mean of a data set?

Back

The mean is the average of all the numbers in a data set, calculated by dividing the sum of the values by the number of values.

Front

What is the difference between a linear function and a non-linear function?

Back

A linear function has a constant rate of change and can be graphed as a straight line, while a non-linear function does not have a constant rate of change and can be graphed as a curve.

Front

How do you find the y-intercept of a line given its equation in slope-intercept form?

Back

The y-intercept is the value of 'b' in the equation y = mx + b, where the line crosses the y-axis.

Front

What is variance in statistics?

Back

Variance is a measure of how much the values in a data set differ from the mean, calculated as the average of the squared differences from the mean.
