Answer with explanation:
The given equation is
→ Py+1=Qx
→Qx-P y=1-----(1)
The given equation is equation in two variable , which represents a line.
To draw a line you need two distinct points.
Put, x=0, in equation 1
Gives, -Py=1

Put, y=0, in equation 1
Qx=1

So, the two points which we have to join to graph this equation is
.
