Answer:
Option: A is correct.
A) a part of a line that has one endpoint and extends indefinitely in one direction
Step-by-step explanation:
" A ray is a line that starts at a given point and goes off for ever in some direction. It may pass through another point as it does so "
Hence, option A is correct.
( The definition of Ray is:
A) a part of a line that has one endpoint and extends indefinitely in one direction )
Answer:
See description below.
Step-by-step explanation:
To choose the correct equation, find the slope of the line on the graph. Identify two points on the line. Then subtract to find their rate of change using the slope formula.

When you know the slope, find the negative reciprocal. For example, if the slope is 2/1 then the negative reciprocal is -1/2. This is the slope of a perpendicular line to a line with slope 2. Choose the equation which has this same slope.
Example:
y = 2x -1
y= -1/2 +5

- How do you simplify this?
- x²y+xy² / y²+2/5 × xy
