During a a math gamaA-Team kept track of the answer the following diagram describe the display the number of answers they got rid of the number they got wrong what is the ratio of the number they got right into the number they got wrong

Distance=slopeslope is -2/4which equals-1/2the distance between these two points is -1/2

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
