Answer:
(2,-4) And (3,-2)
Step-by-step explanation:
Here we have to solve one linear equation and a quadratic equation.
First we find the value of y in terms of x from linear equation and then substitute this value in our quadratic equation to solve it for x , Let us see how :
we have y-2x=8
y=2x-8
Now we substitute this in 
Hence we have

Thus we have
either (x-2)= 0 or (x-3)=0
or x=2 or x=3
Now let us find the value of y by substituting them in y=2x-8 one by one.
y=2(2)-8= 4-8=-4
y+2((3)-8=6-8=-2
Hence our coordinates are
(2,-4) and (3,-2)
