Table of Values - Intro

Front

What is a table of values?

Back

A table of values is a mathematical table used to organize pairs of input (x) and output (y) values for a function.

Front

In a function, what does the 'X' value represent?

Back

The 'X' value represents the input of the function.

Front

In a function, what does the 'Y' value represent?

Back

The 'Y' value represents the output of the function.

Front

What is the general form of a linear function?

Back

The general form of a linear function is y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the output value for a given input in a function?

Back

To find the output value, substitute the input value into the function's equation.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise/run).

Front

What does the y-intercept represent in a linear function?

Back

The y-intercept is the point where the line crosses the y-axis, representing the output value when the input (x) is 0.

Front

How can you create a table of values for a linear function?

Back

Choose several input values (x), substitute them into the function to find the corresponding output values (y), and list the pairs in a table.

Front

What is the output when x = 2 for the function y = 2x + 1?

Back

When x = 2, y = 2(2) + 1 = 5.

Front

What is the output when x = -1 for the function y = -x + 4?

Back

When x = -1, y = -(-1) + 4 = 5.
