Question 17879: through (4,2) and (-4,-2)
Answer by xcentaur(357)   (Show Source):
You can put this solution on YOUR website! (4,2) and (-4,-2)
slope of the line (m) = difference in y-coordinates/difference in x-coordinates
m=2-(-2)/4-(-4)=4/8=1/2
Hence slope of the line=1/2
Taking any point,say(4,2) and using the point-slope form of straight line we get:
(y-2)=m(x-4)
y-2=1/2(x-4)
2y-4=x-4
2y=x
y=x/2
Equation of the line: [y=x/2]
Hope this helps,
