Front

What is the DOMAIN of a graph?

Back

The DOMAIN of a graph refers to the set of all possible input values (x-values) for which the function is defined.

Front

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

Back

The m represents the slope of the line, indicating how steep the line is.

Front

What is the DOMAIN of the graph defined by -7≤x<5?

Back

The DOMAIN is the set of x-values from -7 (inclusive) to 5 (exclusive).

Front

Write the equation of a line in point-slope form that passes through (3,8) and has a slope of 5.

Back

The equation is y-8=5(x-3).

Front

What does the inequality 4x-y>5 represent graphically?

Back

It represents the region above the line 4x-y=5 on a graph.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What is a linear equation?

Back

A linear equation is an equation that forms a straight line when graphed, typically in the form y=mx+b.

Front

What does it mean for a function to be defined?

Back

A function is defined for a particular input if there is a corresponding output value.

Front

What is the difference between an open interval and a closed interval?

Back

An open interval does not include its endpoints, while a closed interval includes its endpoints.
