The slope is 1.5, and the y-intercept is -2.
Remember the equation y = mx + b

Explanation:</h2>
Here we have the following expression:

So we need to extend this. Remember that the difference of squares tells us:

So here:

Thus:

Answer:
D(-5,3) and E(-5,1)
Step-by-step explanation:
|AB|² = (-1-5)² + (-6-2)²
|AB|² = 36 + 64
|AB|² = 100
|AB| = 10
AB/DE = 5
|DE| = 10/5 = 2
D(-5,3) and E(-5,1)
|DE|² = (-5+5)² + (3-1)²
|DE|² = 4
|DE| = 2
