Answer:
Given equation,
-7y + 8 = 21 x - 6,
8 + 6 = 21x + 7y
⇒ 21x + 7y = 14
Which is the equation of line,
If x = 0,
21(0) + 7y = 14
7y = 14 ⇒ y = 2
⇒ Point (0, 2) is on the line,
If y = 0,
21x + 7(0) = 14
21x = 14 ⇒ x = 2/3
⇒ Point (2/3, 0) is on the line,
Hence, we can graph the given line by joining the points (0, 2) and (2/3, 0) in the coordinate plane. ( shown below )
