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 )
