Question

Will give medal for answer
The graph of a line passes through the two points (-2, 1) and (2, 1). What is the equation of the line written in general form?


y - 1 = 0
x - y + 1 = 0
x + y - 1= 0

Answer 1

find the slope, with formula y2-y1/x2-x1
what do you get

Answer 2

exactly...find the slope first..
slope(m) = (y2 - y1) / (x2 - x1)
(-2,1) x1 = -2, y1 = 1
(2,1) x2 = 2, y2 = 1
now sub your stuff in

Answer 3

Let me start you off...
m = (1 - 1) / (2 - (-2)
