Question

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

Answer 1

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
