Question

Sam is observing the velocity of a car at different times. After two hours, the velocity of the car is 54 km/h. After four hours, the velocity of the car is 58 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 six hours? (5 points)

Answer 3

yes :)

Answer 4

im stuck on this question if you can help

Answer 5

i can help you
:)

Answer 6

The question is up there

Answer 7

say velocity = v, and time = t

Answer 8

okay

Answer 9

okay but it says in standard form

Answer 10

nope

Answer 11

start by finding the slope

Answer 12

so y2-y1/x2-x1?

Answer 13

slope is 1/2

Answer 14

2/1

Answer 15

okay but its really (2,54) (4,58) 58-54=4/2= 2

Answer 16

so the required equation will be of form :

v=2t+b

you need to find b by plugging in one of the given points

Answer 17

like what

Answer 18

v=2t+50

Answer 19

were did you get 50?

Answer 20

form your slops

Answer 21

so now we have to convert to standard form

Answer 22

\(\huge\color{lime}yes\)

Answer 23

okay

Answer 24

okay do you kind of get it ?
