Front

How do you determine 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 -3/2, what does this indicate about the line's direction?

Back

The line is decreasing.

Front

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

Back

The point where the line crosses the y-axis.

Front

How can you identify the slope from the equation y = mx + b?

Back

The slope is the coefficient of x (m).
