Since y = x + 13 you have only to replace x with values on the table:
- for x = -10 => y = -10 + 13 = -3
 - for x = -7 => y = -7 + 13 = 6
 - for x = -6 => y = -6 + 13 = 7
 - for x = -5 => y = -5 + 13 = 8
 
Now we have the coordinates of the points (x, y):
- (-10, -3)
 - (-7, 6)
 - (-6, 7)
 - (-5, 8)
 
Now draw the points and connect them. I hope this helped.
