The graph of the equation x – 7y = – 42, intersects the y-axis at P (α
| The graph of the equation x – 7y = – 42, intersects the y-axis at P (α, β) and the graph of 6x + y – 15 = 0, intersects the x-axis at Q(γ, δ). What is the value of α + β + γ + δ?
A.
B. 5
C. 6
D.
Right Answer is: D
SOLUTION
When the line intersects the y-axis then,
Hence,
When the line intersects the x-axis then,
Henve the value of
