Use the formula m = y2-y1/x2-x1to calculate the slope of the line. The slope of the line is (___) The coordinates are 2,8 and (-6,-8).

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.
