Answer:
x = 9
y = 6
Step-by-step explanation:
ΔABC ~ ΔPQR
Therefore, corresponding sides of these similar triangles will be in the proportional.



x = 
x = 9
Similarly, 
y = 
y = 6
The answer is y= 1 + 1x
because the slope is 1 shown by this table:
1,2
2,3
3,4
4,5
and if the slope is one then 2-1 is 1 and the y intercept is 0,1.
No the answer to the solution would be 7
