(x1,y1) = (2000,1000)
(x2,y2)= *(2012,3400)


slope = (y2-y1) / (x2-x1) = 2400 / 12 = 200


y = mx + b is slope intercept form of linear equation.
m is the slope.
b is the y-intercept.


replace m with 200 and you get:


y = mx + b becomes y = 200x + b


replace y and x with the values of one of the coordinate points and then solve for b.


we'll use (x1,y1) = (2000,1000)


y = mx + b becomes 1000 = 200*2000 + b


solve for b to get b = 1000 - 200*2000 = 1000 - 400000 = -399000


y = mx + b becomes y = 200x - 399000


when x = 2000, y = 200*2000 - 399000 = 400000 - 399000 = 1000


when x = 2012, y = 200*2012 - 399000 = 402400 - 399000 = 3400


your equation is y = 200x - 399000.
