1Complete each step, then write the final answer.
Which quadrant is the point (4, −6) in?
Show your workHint x is positive, so move right. y is negative, so move down.
Final answer: -
2Complete each step, then write the final answer.
Which quadrant is the point (−7, 3) in?
Show your workHint Read the sign of x, then the sign of y.
Final answer: -
3Complete each step, then write the final answer.
On a city map, City Hall is at (0, 0). The library is 2 blocks west and 5 blocks north of City Hall. East and north are positive. Which quadrant is the library in?
Show your workHint West is the opposite of east. Write the ordered pair first.
Final answer: -
4Complete each step, then write the final answer.
A point starts at (−3, 2). It moves 5 units right and 4 units down. Which quadrant is the new point in?
Show your workHint Right changes x. Down changes y. Find the new ordered pair first.
Final answer:
Explain your thinkingTia used the numbers in the wrong order and ignored a sign. How do you plot an ordered pair the right way?
