What is the y-intercept of the linear function $$y = 2x + 3$$ ?

The y-intercept is the point where the line crosses the y-axis. For the function $$y = 2x + 3$$ , the y-intercept is $$3$$ .

How do you solve the equation $$3x + 5 = 2x + 9$$ ?

To solve for $$x$$ , first subtract $$2x$$ from both sides: $$x + 5 = 9$$ . Then, subtract $$5$$ from both sides to get $$x = 4$$ .

Calculate the standard deviation of the data set $$[2, 4, 4, 4, 5, 5, 7, 9]$$ .

The standard deviation of the data set $$[2, 4, 4, 4, 5, 5, 7, 9]$$ is $$2$$ .

How do you solve the equation $$4(x - 2) = 2x + 8$$ ?

First, distribute $$4$$ : $$4x - 8 = 2x + 8$$ . Then, subtract $$2x$$ from both sides: $$2x - 8 = 8$$ . Finally, add $$8$$ to both sides to get $$2x = 16$$ , so $$x = 8$$ .

What does it mean to solve a multi-step equation?

Solving a multi-step equation involves performing multiple operations to isolate the variable on one side of the equation. This may include combining like terms, distributing, and using inverse operations.

Calculate the standard deviation of the data set $$[5, 10, 10, 15, 20]$$ .

The standard deviation of the data set $$[5, 10, 10, 15, 20]$$ is $$5$$ .

What is the slope of the line represented by the equation $$y = 2x + 3$$ ?

The slope of the line is the coefficient of $$x$$ in the equation. For $$y = 2x + 3$$ , the slope is $$2$$ .

What is the first step in solving the equation $$3x + 5 = 2x + 9$$ ?

The first step is to isolate the variable $$x$$ by subtracting $$2x$$ from both sides, resulting in $$x + 5 = 9$$ .

What is the mean of the data set $$[2, 4, 4, 4, 5, 5, 7, 9]$$ ?

The mean is calculated by adding all the numbers together and dividing by the count of numbers. For this data set, the mean is $$5$$ .

What is the purpose of finding the y-intercept in a linear function?

The y-intercept helps to understand where the line crosses the y-axis, providing a starting point for graphing the function.

What is the relationship between the slope and the y-intercept in a linear equation?

In a linear equation of the form $$y = mx + b$$ , $$m$$ represents the slope (rate of change) and $$b$$ represents the y-intercept (the value of $$y$$ when $$x = 0$$ ).

What does it mean if a data set has a standard deviation of 0?

A standard deviation of 0 means that all the values in the data set are identical, indicating no variation among the data points.

What is standard deviation?

Back

Standard deviation is a measure of the amount of variation or dispersion in a set of values. A low standard deviation means that the values tend to be close to the mean, while a high standard deviation means that the values are spread out over a wider range.
