Answer:
D) 3x + y = 5 and 2x -3y = 7
Step-by-step explanation:
You can plug in the x and y values into the equations, and see if they work. In this case, 3x + y = 5 and 2x -3y = 7 both satisfy (2, -1).
Answer:
B
Step-by-step explanation:
This is because when you reflect a triangle the letters need to be the same distance from the point of reflection (the y axis) when you count everything out B is the only answer with all of the correct coordinates.

Answer: i think it’s A and D
Answer:
y=(1/2)x+3
Step-by-step explanation:
We can see that the slope is 1/2 because for every 1 unit y goes up, you move 2 units in the x direction. Then we can see that the y intercept is 3.
If we plug in these values to our equation for a line (y=mx+b), where m is the slope and b is the y-intercept, we get:
y=(1/2)x+3 or y=.5x+3
