you have 2 points on the line (x1, y1) and (x2, y2) 
you can find the slope of the line 
m = (y2- y1)/ (x2 - x1) 
using one of the points give you can use y = mx + b to find b
now write the general equation for any point on this line (x, y)

triciaal · Answer

notice the line is left to right going down slope is negative

triciaal · Answer

not marked but when x = 0 y = 110  this is your b   the intercept

anonymous · Answer

110?

triciaal · Answer

do you see the slope is -40/20 = -2 
y = -2 x  + 110
