I only need Part B.. FAN AND MEDAL :) Sam is observing the velocity of a car at different times. After three hours, the velocity of the car is 51 km/h. After five hours, the velocity of the car is 59 km/h. Part A: Write an equation in two variables in the standard form that can be used to describe the velocity of the car at different times. Show your work and define the variables used. Part B: How can you graph the equation obtained in Part A for the first six hours?

    if t =2, then V_2 = 4*2 +39 = 47, the second point is (2,47)|dw:1443023918657:dw|

    Do the same for t =3,4,5,6 then link the points to have the graph.

    Your question: " How to graph" My answer: find out the points, link them together. That is the way you graph.
