1) Division Property Equality
first pass: Simplify by 8
second pass: <span>Now divide the equals
</span>
2) Addition Property of Equality
first pass: <span>Incognito on the left and numbers without incognito on the right, changing signs if they change sides.
</span>
second pass: Do the addition
<span>
3) Subtraction </span>Property of Equality
first pass: Incognito on the left and numbers without incognito on the right, changing signs if they change sides.
second pass: Do the subtraction
<span>
4) Multiplication Property of Equality
</span>
first pass: <span>Multiply the equalities by the inverse of the incognito, without the incognito
</span>
second pass: <span>Cancel the same terms and divide the ratio.
</span>
5) Distributive Property
<span>first pass: We only evaluate what is in the parentheses first and then we solve it.
</span>
second pass: we just evaluate what’s in the parentheses first, then solve it. We have a distributive property, with the distributive property, we multiply the '7' first.
Obs: <span>This question is not to find the value, only to show the distributive property.
</span>
<span>For better understanding and solve your question with equation with incognito, after the distributive property, equalize the terms to zero, then isolate the terms, putting numbers with incognito on the left and numbers without incognito on the right, changing the signal as they change sides. And then solve by finding the value of the incognito dividing the terms.

Answer: Line slopes:
m1= 3/2 defined by points (5,3) and (7,6)
m2= -2/3 defined by points (7,6) and (4,8)
m3 = 3/2 defined by points (4,8) and (2,5)
m4 = -2/3 defined by points (2,5) and (5,3)
All comply the orthogonal slopes rule (90º)
Step-by-step explanation:
As those 4 point define a polygon, to check is that polygon is a rectangle, you need to compare the slopes of the lines defined by the 4 points and check that accomplish the following rule:
m1 = -(1/m2). this shows that the slopes are intersected in 90º angle.
