Recall that the slope of a line is a ratio of the rise to the run. If a line has a slope of 3/5 and you have chosen two points on the line that have a rise of 15, what is the run?

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.

Value is 6 i think k
