Answer:
It's when rates are expressed as quantities.
Step-by-step explanation:
An example would be miles per hour (mph). People use these to determine the distance they will go in an amount of time and to judge safe speed.
Simple, since you want to find y, in y=mx+b form, move everything to the other side.
1/2x-y=4
Move 1/2x
1/2x-y=4
-1/2x -1/2x
Making it look like,
-y=4-1/2x
Divide by the negative 1 in front of the y,
-y=4-1/2x
/-1 /-1
y=-4+1/2x
or
y=1/2x-4
Thus, this written in y=mx+b form, y=1/2x-4.
The value of x would be 67 because the lines are parallel and form a linear pair.
