Is the Analysis of H(x)=4 as a Linear Function Correct?

In summary, a simple linear function is a mathematical relationship between two variables, represented by the equation y = mx + b. To graph it, plot two points or use the slope and y-intercept values. A positive slope indicates a direct relationship, while a negative slope indicates an inverse relationship. The slope can be found by dividing the change in y-values by the change in x-values, or by using the slope formula. The y-intercept represents the value of the dependent variable when the independent variable is zero and is useful for making predictions or interpreting the meaning of the slope in real-world scenarios.

[SOLVED] Simple Linear Function

1.Determine the slope, average rate of change, and y intercept of H(x)=4
3.I believe the Y intercept is 4, the slope is 0 and the avg. rate of change is 0. Is this correct?

Also, does "linear" mean it must be a straight line?

"the Y intercept is 4, the slope is 0 and the avg. rate of change is 0" is correct.

Loosely, linear means straight line, but technically it may also mean the intercept is zero. (In the loose interpretation the intercept does not have to be zero.)

Thank you.
 

1. What is a simple linear function?

A simple linear function is a mathematical relationship between two variables, where the dependent variable changes at a constant rate as the independent variable changes. It can be represented by the equation y = mx + b, where m is the slope and b is the y-intercept.

2. How do you graph a simple linear function?

To graph a simple linear function, plot two points on the coordinate plane that satisfy the equation y = mx + b. Then, draw a straight line through those two points. Alternatively, you can use the slope and y-intercept values to plot the y-intercept as the first point, and then use the slope to plot additional points and connect them to create the line.

3. What is the difference between a positive and a negative slope in a simple linear function?

A positive slope indicates a direct relationship between the two variables, where the dependent variable increases as the independent variable increases. A negative slope indicates an inverse relationship, where the dependent variable decreases as the independent variable increases.

4. How do you find the slope of a simple linear function?

The slope of a simple linear function can be found by dividing the change in the y-values by the change in the x-values between two points on the line. This can also be calculated using the slope formula, which is (y2 - y1) / (x2 - x1).

5. What is the significance of the y-intercept in a simple linear function?

The y-intercept represents the value of the dependent variable when the independent variable is equal to zero. It is often used to make predictions or interpret the meaning of the slope in real-world scenarios.
