Step-by-step explanation:
The standard form for a line is Ax+By=C
First, we need to find the slope, or change in y over change in x. For the first one, this is
, which is impossible to find as we cannot divide by 0, meaning that this is constant horizontally -- in this case, x=2. Thus, we have 1*x+0*y=2.
For the second one, we can find the slope by getting
. We can then take the point (3,0) (it can be any point on the line) and get our equation to be y-0 = (-2/3) (x-3). Converting this to standard form, we can expand this to get
y= (-2/3)*x +2
(-2/3)*x+1*y = 2

Answer:
9.33 seconds
60.67 meters
Step-by-step explanation:
A worker with a speed of 3.0 m/s with respect to a car, starts to walk from one end of the car to the other in the direction of motion of the car.
As the car is 28 m long, then the worker will reach the other end of the car in 
seconds. (Answer)
Now, the car is moving with a speed of 6.5 m/s and in the time of 9.33 seconds, it will move by 
meters. (Answer)
A), e), and g) are the correct answers
