What is the standard form equation of the line shown below? Graph of a line going through negative 2, 3 and 1, negative 3

1. y + 3 = −2(x − 1)
2. y = −2x − 1
3. 2x + y = −1
4. −2x − y = 1

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.
