Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is the equation of a line in slope-intercept form?

Back

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

Front

What is a zero of a function?

Back

A zero of a function is a value of x that makes the function equal to zero.

Front

How can you determine if a function has a zero at x = -5?

Back

Substitute -5 into the function and check if the output is zero.

Front

What does the inequality 4x - 2y ≤ 8 represent graphically?

Back

It represents a region on the coordinate plane where the line 4x - 2y = 8 is a boundary.

Front

How do you graph an inequality like y ≥ 2x - 4?

Back

Graph the line y = 2x - 4, then shade above the line.

Front

What is the line of best fit?

Back

The line of best fit is a straight line that best represents the data on a scatter plot.
