If three points (x1,y1),(x2,y2) and (x3,y3) are collinear ,then

• $\frac{y_2-y_1}{x_2-x_1}=\frac{y_2-y_3}{x_2-x_3}$

In the figure, time and distance graph of a linear motion is given. Two positions of time and distance are recorded as when T=0 ,D=2 and when T=3,D=8.Using the concept of slope, find law of motion, the relationship between D and T

• D= 2(T-1)

• T=2(D+1)

• T=2(D-1)

• D=2(T+1)
