The square root of a number is multiplying that number by its self so like 2² which is 2 squared. the answer would be 2 x 2 = 6 hope this helps!
Your question is a bit unclear, but if you mean which lines are parallel to this one then I have an answer.
1/2*4=2 so this line would be y=2 which means it is a horizontal line. Therefore, any other horizontal line would be parallel to it. So just pick a value for Y to equal and that will be your answer.
ie. y=7
15 cherry, 17 grape, and 14 orange....total of 46 juice boxes
P(cherry) = 15/46
without replacing
P(grape) = 17/45 (I put it over 45 because since the 1st was not replaced, we have 1 less juice box)
P (both events happening) = 15/46 * 17/45 = 17/138 <==
-4 and 2 are the solutions, since that is where they intercept the x axis, and when plugged into the equation, make it true.
