7. Write a rule for the linear function shown in the graph.

A. y = 5/4x - 2

B. y = -4/5x + 2

C. y = 4/5x + 2

D. y = –5x – 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.
