Question

Two lines, C and D, are represented by the equations given below:

Answer 1

Given:
line C: y = x + 14
line D: y = 3x + 2

(6,20) or (3,11)

line C: y = 6 + 14 = 20  or y = 3 + 14 = 17
line D: y = 3(6) + 2 = 18 + 2 = 20   or  y = 3(3) + 2 = 9 + 2 = 11

(6,20), because both lines pass through this point.
