1. Linear Equations



1) x + 7 = 20 Subtract 7 from both sides: x = 20 - 7
Result: x = 13

2) 3x - 4 = 11 Add 4: 3x = 15
Divide by 3: x =
Result: x = 5




2. Slope



1) (1, 2) and (5, 10) Formula: m = (y2 - y1) / (x2 - x1)
m = (10 - 2) / (5 - 1) =
Slope (m) = 2

2) (3, 4) and (7, 4) m = (4 - 4) / (7 - 3) =
Slope (m) = 0
