Answer:
(B)(0,5)
Step-by-step explanation:
Given the start point at (4,1)
Given the (x,y) coordinates
- Moving to the left 4 places is: x-4
- Moving up 4 places: y+4
Therefore, applying the rule to (4,1), we have:
(4-4, 1+4)=(0.5)
The coordinates of the new ordered pair is (0,5).
The correct option is B.
Answer:
13. y = -4x + 6
14. y = 1/2x - 2
Step-by-step explanation:
You want to put y on one side and the rest of the numbers on the other side. You can do this by adding or subtracting or dividing the numbers/variables on the left.
13.
4x + y = 6
subtract both sides by 4x
y = 6 - 4x
or rewritten as:
y = -4x + 6
14.
-3x + 6y = -12
add both sides by 3x
6y = 3x - 12
divide both sides by 6
y = 1/2 x - 2
please give thanks :)
