(Section 0.14: Lines) 0.14.8 y = ± 11 6 x + 4 () + 5 y = ± 11 6 x ± 44 6 + 5 y = ± 11 6 x ± 22 3 + 15 3 y = ± 11 6 x ± 7 3 Method 2 (Substitute Directly into Slope-Intercept Form) In Slope-Intercept Form , y = mx + b , x and y are variables that must stay in the final equation. We know that m = ± 11 6 . We need to find b . According to the Basic Principle of Graphing , x = ± 4, y = 5 ()
