Answer:
Step-by-step explanation:
The triangle ABC(on the right hand side) is mirrored about the y-axis and translated one unit in the direction of the negative y-axis and the result the triangle DFE(on the left hand side)
Note that the same result can be obtained by translating then mirroring.
The Size(Area) is actually the same.
So basically If its coordinates was ( x , y )
it's now ( -x , y-1 )
(- minus) Due to Mirroring
(-1) duo to Translating in the negative direction
A south pole of one magnet can approach the north pole of another. The magnetic fields are aligned. This makes an attractive force between the two magnets. The farther apart they are, the higher their potential energy.

Answer:
y = x + 4
Step-by-step explanation:
Well, the important thing is to get the slope first. The slope here is 1.
Here's how to find the slope yourself:
m (slope) = (y₁ - y₂)/x₁ - x₂
m (slope) = (3 - 4)/(-1 - 0)
m (slope) = -1/-1
m (slope) = 1
So, we found the slope. Now, plug it into the equation. y = 1x + b. Cool, so now let's choose the first point to solve this.
So, 3 = 1(-1) + b
3 = -1 + b
3+1 = -1+1 + b
The ones cancel out...
4 = b
So, now you plug that into the equation... y = 1x + 4, although you would write it as y = x + 4.
When x is equal to 0, the -2/3 becomes 0. Because 0 times anything equals zero.
y is equal to 4
