Answer:

D) (2,6)

Step-by-step explanation:

y - 2 = 2x ---------(i)

y = 4x - 2 --------(ii)

substitute y = 4x-2 in equation (i)

4x-2 - 2 = 2x

4x - 4 = 2x

4x - 2x = 4

2x = 4

x = 4/2

x = 2

Now plug in the x value in equation (ii)

y = 4*2 - 2

y = 8-2

y = 6

Alright, lets get started.

Lets find slope for both bikes one by one

For bike 1 :

There are two points on the graph of Bike 1, these two points are (2,3) and (4,6)

So the slope for bike 1 is : $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

So the slope for bike 1 is : $\frac{6-3}{4-2}$

So the slope for bike 1 is : $\frac{3}{2}$

For bike 2 :

There are two points on the graph of Bike 2, these two points are (4,5) and (8,10)

So the slope for bike 2 is : $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

So the slope for bike 2 is : $\frac{10-5}{8-4}=\frac{5}{4}$

Hence Bike 1 will win the race as slope of line bike1 is greater than slope of line bike 2. So, answer is option D
