Answer:
1. Y
2. N
3. N
4. N
Step-by-step explanation:
Let's use the second equation, since it seems to be easier to use.
To check if an ordered pair is a solution, plug it in to the equation.
1.
--> Y
2.
--> N
3.
--> N
4.
--> N
Edit : The 4th equation doesn't work for the first equation, whereas the first one still does.
The answer is c! As CBA & ZXY is not only a full triangle, but its written incorrectly.
ABC → CBA
XYZ → ZYX (not ZXY)
Answer:
b
Step-by-step explanation:
Step-by-step explanation:
4x -y =2
-y = -4x + 2
y = 4x -2
slope = 4
perpendicular slope is negative inverse
so -1/4
y- -2 = -1/4(x - 4)
y+2 = -1/4x +1
y = -1/4x -1
