Front

What is the formula for calculating the slope of a line?

Back

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

Front

If the slope of a line is -5/4, what does this indicate about the line's direction?

Back

The line is decreasing (going down from left to right).

Front

If the slope of a line is 7/5, what does this indicate about the line's direction?

Back

The line is increasing (going up from left to right).

Front

Front

What is the relationship between complementary angles?

Back

Complementary angles add up to 90 degrees.

Front

What is the relationship between vertical angles?

Back

Vertical angles are equal.

Front

What is the formula for finding the slope between two points (x1, y1) and (x2, y2)?

Back
