The endpoints of on are located at o(1,2) and n(3,1). using slope intercept form, write the equation of line on
a. y= -2x+4
b. y= -1/2x+5/2
c. y=1/2x+3/2
d. y=2x

First find the slope using
(y2-y1)/(x2-x1)
(1-2)/(3-1)=-1/2
Since only one answer has s slope of -1/2 the answer is B

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.
