Question

medal and fan!

Answer 1

Sam is observing the velocity of a car at different times. After two hours, the velocity of the car is 50 km/h. After six hours, the velocity of the car is 54 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. (5 points)

Part B: How can you graph the equation obtained in Part A for the first seven hours? (5 points)

Answer 2

@welshfella can you help?

Answer 3

say velocity = v, and time = t
(2,50)(6,54)
slope(m) = (54 - 50) / (6 - 2)
slope(m) = 4/4
slope(m) = 1

y = mx + b
50 = 1(2) + b
50 = 2 + b
48 = b

equation is : y = x + 48 y = total km/hr and x = number of hrs

put what?

Answer 9

the graph

Answer 10

can you explain how i could graph the equations from part A

Answer 11

you can make a table and then plot the points
