Show Answer to the Exercise:
























bAB : 4x + 5y – 33 = 0; bAC : 7x – 4y + 6 = 0; bBC : x – 3y + 30 = 0
 lie on one straight line parametric equations: x = 3 – 4t; y = 4 – 2t; t∈R general equation: x – 2y + 5 = 0 slope-intercept equation: y =


p: x = 2 + t; y = –1 – t; z = 2 + t; t∈R
parametric equations: x = –4 + 2t + 3s; y = t – 4s; z = 2 – t – 3s; s,t∈R general equation: 7x – 3y + 11z + 6 = 0
α : x – 2y + 5z – 20 = 0
σ : x – 2y + 2z + 3 = 0
BCV : 3y + z – 12 = 0
