What is the slope of a line?

Back

The slope of a line is a measure of its steepness, typically represented as 'm'. It is calculated as the change in y divided by the change in x (rise over run).

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

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line, where the change in x is zero, leading to division by zero.

What does the absolute value equation |3x - 6| = 18 represent?

Back

It represents two equations: 3x - 6 = 18 and 3x - 6 = -18.

What is the error in the equation 15 - 3x = 2x - 2 when adding 2x?

Back

The error is that instead of adding 2x, you should subtract 2x to maintain equality.

How do you solve the equation |x - 4| = 10?

Back

The solutions are x - 4 = 10 and x - 4 = -10, leading to x = 14 and x = -6.
