You can put this solution on YOUR website! (0,8),(1,6),(2,4),(3,2),(4,0).......
take any two points and find a equation of straight line given 2 points
(0,8),(1,6)

hahaWe are trying to find equation of form y=ax+b, where a is slope, and b is intercept, which passes through points (x1, y1) = (0, 8) and (x2, y2) = (1, 6).
Slope a is  .
Intercept is found from equation  , or  . From that,
intercept b is  , or  .
y=(-2)x + (8)
Your graph:

a equation is:
check for other two points
(3,2),(4,0)
