Front

What is the significance of the slope in a linear equation?

Back

The slope of a linear equation indicates the rate of change of the dependent variable with respect to the independent variable, representing the steepness of the line.

Front

What is the formula for calculating the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = 1/2 * base * height.
