Estimating the Gradient of a Graph: Student's Attempt
Reply to thread
Message
[QUOTE="WWGD, post: 6825320, member: 69719"] Well, the points (1,2) and (0.9, 1.8) defines the line y2=2x, which contrasts with the line y1-1=1.386(x-2). Maybe a bound/estimate for |y1-y2| would help explain why the choice of (0.9, 1.8) was not as good. Additionally , comparing it with the choice of {(1,2),(3,5)} which would define the line y3-2=2(x-1). Maybe we can find a generic value for |y-y1|, for y=mx+b. Hope I'm not too far of. [/QUOTE]
