Slope, Perimeter and Area of figure in a plane

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2(length + width).

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

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

Back

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

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis (x=0).

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 × base × height.

Front

What is the formula for the perimeter of a triangle?

Back

Perimeter = side1 + side2 + side3.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope.

Front

What is the formula for the area of a circle?

Back

Area = π × radius².

Front

What is the formula for the circumference of a circle?

Back

Circumference = 2π × radius.
