  1. 5 - no idea
    8 - no idea
    7 - NO - y is the same, x changes sign
    so (-8,-10) the first on the list

  2. #5,#8 no idea - no diagram
    #7 (-8,-10)
    (-8,10) is reflected through the origin.

    8. (I recommend writing this in YOUR OWN words so you are not plagiarizing and this doesn't get traced back.) *THINK SMARTER NOT HARDER!*
    To get the square root of imperfect square we can use the formula , which is usually accurate to about two decimal places,√X =√S +(X-S)2√SWhere, X = the number you want the square roof of, and S is the closest square you know to x.For example 75 is an imperfect squareThus, X=75 and thus the nearest number S = 81, this ,means √81 =9.Putting this into the formula;√75= 9+(75-81)/2/2(9) = 9 + -6/18 = 9-0.33333 = 8.667= 8.667, thus the square root of 75 is 8.66
