Q2. Formula to find midpoint and slope of a line
Ans. 
Midpoint and slope formulas help determine key characteristics of a line in coordinate geometry.
• Midpoint formula: M = ((x1 + x2)/2, (y1 + y2)/2). Example: M = ((1 + 3)/2, (2 + 4)/2) = (2, 3).

• Slope formula: m = (y2 - y1) / (x2 - x1). Example: m = (4 - 2) / (3 - 1) = 1.

• Midpoint gives the center point between two coordinates.

• Slope indicates the steepness and direction of the line.
