Answer: 0 = -4x + b
Step-by-step explanation: Write -4x as -4 over 1 (-4/1) and using rise over run you move down 4 and right 1. Then you move up 4 and left 1. Plot those two points where you stopped. That doesn't matter though in this case, you only need the equation.
A simple way to find an equivalent fraction to
is to multiply both denominator and numerator.
So:
Yes it describes a direct variation because y is 4x distance Is 4 times of time x
The point slope form of the line is:
D. y+4=2/5(x+7)
