Front

What does the slope of a linear equation represent?

Back

The rate of change of y with respect to x.

Front

What is a y-intercept in a linear equation?

Back

The value of y when x is 0.

Front

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

Back

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

Front

What is the general form of a linear equation?

Back

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

Front

If the slope of a line is negative, what does that indicate about the line's direction?

Back

The line decreases as it moves from left to right.
