Anyone?

anonymous · Answer

try to drawing the graph

anonymous · Answer

to make a line we need two points

anonymous · Answer

2P = 12 - 2Q
let Q = 1, then we substitute into the equation to obtain P

anonymous · Answer

$$Q=1\rightarrow 2P = 12 - 2 \left( 1 \right)$$

anonymous · Answer

Can you continue?

anonymous · Answer

2P = 12 -2
2P = 10
P = 10/2
P = 5

anonymous · Answer

I dont think so, still didnt get it

anonymous · Answer

so we have a point (P, Q) = (1,5)

anonymous · Answer

to draw a graph, we have to look for two point in the graph

anonymous · Answer

ah alright

anonymous · Answer

we already have one point, meaning we are now looking for another point

anonymous · Answer

try for different Q values

anonymous · Answer

Can you try it?

anonymous · Answer

yeah thanks
