All points in a plan 4 units from point P
that is a circle
defenition is the set of all points the same distance from a given point
CIRCLE
The equation above, y = -2/3x, takes into the form of y = mx + b where m is the slope and b is the y-coordinate which is equal to zero in this case. The slope of the line is therefore -2/3. A line having a negative slope tilts to the left. Thus, the answer is b. tilted right downwards.
Answer: You plug in a value for one of the variables
Step-by-step explanation: For example f(x)=2x+2
x=6 2(6) +2=14
