Problem with alloc ant init - ObjC

This is the Challenge: Create an NSMutableDictionary called 'carDict'. Allocate memory and initialize 'carDict' with the following key/value pairs: "Make":"Honda", "Model":"Accord". Do this all in one line of code.

Thanks for the helping.

NSMutableDictionary *carDict;

carDict = [NSMutableDictionary alloc];

[carDict initWithObjectsAndKeys: @"Make", @"Honda", @"Model", @"Accord", nil];
