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)

Each time the x value goes up by 1 the y value decreases by 2 so the slope is -2/1 or just -2

 

Also when x = 0 the y value (the intercept) is 8

 

Hence y = -2x + 8

You were right, because the result is the equation of a straight line!
