Answer:3x + 7y = 63
Explanation:The equation of PQ is
y = -(3/7)x + b
To find b, note that the line passes through the point (7,6). Therefore
6 = -(3/7)*7 + b
6 = -3 + b
b = 9
The equation of PQ is
y = - (3/7)x + 9
or
7y = -3x + 63
3x + 7y = 63
According to the graph, the prediction on the future is that there will be c. resource depletion.
<h3>What does the graph show?</h3>
The graph shows that as time goes on, humanity will demand more and more hectares of forest.
This will lead to forests eventually being wiped out after around 700 years which points to resource depletion.
