Why are the equations w - x x = w and w x - x = w called identities?

saveliy_v [14]

They are called identities because:
w-x = 0
w = x (carry x to the other side) is the same as x = w

in the other case:
wx-x = w / divide by w on both side
x -x = 0
x = x (carry x to the other side)

In both cases the equations are the same.

Answer:

Step-by-step explanation:

Use rise over run, (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(8 + 20) / (5 - 3)

28 / 2

= 14
