(0,0)(1,2)...these are 2 sets of points I picked off the line
slope(m) = (y2 - y1) / (x2 - x1)
slope(m) = (2-0) / (1-0) = 2/1 = 2
y = mx + b
slope(m) = 2
use either of ur sets of points (1,2)..x = 1 and y = 2
now we sub and find b, the y int
2 = 2(1) + b
2 = 2 + b
2 - 2 = b
0 = b
so ur equation is : y = 2x + 0...or just y = 2x
