i) The "explain" part of standard A-REI.11 is not assessed here. For this aspect of the standard, see Sub-Claim C.
Sample Questions (taken from PARCC’s Practice Tests and Released Items):

PBA Released Test Item 4
EOY Released Test Item 29
Practice Test, Unit 2, Item 2
Paper Test, Unit 2, Item 16  1. PBA Released Test Item 4
Graph lines m and t on the xy-coordinate plane shown. Then plot the point of intersection P.
Line m : y = -2/3 x - 4
Line t : y = x + 6
To graph a line, select two points on the coordinate plane. A line will be drawn through the points. Select the place on the coordinate plane to plot the point. 2. EOY Released Test Item 29 The graph of f(x) = -x3 - 4 and g(x) = 0.5x2 + x + 4 are given. Use the graphs to find the solution to the equation
-x3 -4 = 0.5x2 + x + 4.
