Front

Find the slope of the line that passes through the points (2, 4) and (6, 12)

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1). For points (2, 4) and (6, 12), m = (12 - 4) / (6 - 2) = 8 / 4 = 2.

Front

Calculate the area of a rectangle with length 12 feet and width 8 feet.

Back

Area = length x width = 12 ft x 8 ft = 96 square feet.

Front

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

Back

The formula for slope (m) is m = (y2 - y1) / (x2 - x1).

Front

What is the area of a triangle with a base of 10 units and a height of 5 units?

Back

Area = (1/2) x base x height = (1/2) x 10 x 5 = 25 square units.

Front

How do you convert a decimal to a fraction?

Back

To convert a decimal to a fraction, write the decimal over 1, multiply numerator and denominator by 10 for each digit after the decimal, and simplify.

Front

What is the formula for the area of a rectangle?

Back

The formula for the area of a rectangle is Area = length x width.
