Inv 2.3 Solving Linear Equations
One step equations:
9 = b + 4 -4 = h + 3 5 = x – 2
-4 -4 -3 -3 +2 +2
5 = b -7 = h 7 = x
Two step equations:
13 = 4x + 5 -6 = 2p – 2
-5 -5 +2 +2
8 = 4x -4 = 2p
4 4 2 2
2 = x -2 = p
Solving for y-intercept:
M = 2; ( 3 , 2 ) m = -3; ( 1 , 4 ) x y x y 2 = 2(3) + b 4 = -3(1) + b
2 = 6 + b 4 = -3 + b -6 -6 +3 +3 -4 = b 7 = b
