1. Algebra:The Equation of the Line

2. (1 , 2) (3 , 4) The Formula of The Equation of the line is: y = mx + b

3. (1 , 2) (3 , 4) The Formula for the Slope (m): m = The slope (m) = 1

4. The Formula of The Equation of the line. y = mx + b y = 1x + b Solve for “b”: (1 , 2) y = 1x + b 2 = 1 + b b = 2 – 1 b = 1 (1 , 2) (3 , 4)
