Answer:
B. 
Step-by-step explanation:
we know that
If a ordered pair is a solution of a linear equation. then the ordered pair must satisfy the linear equation
In this problem we have

<u>verify each case</u>
case A) 
substitute the value of x and the value of y in the linear equation and then compare

-----> is not true
therefore
The ordered pair case A) is not a solution
case B) 
substitute the value of x and the value of y in the linear equation and then compare

-----> is true
therefore
The ordered pair case B) is a solution
case C) 
substitute the value of x and the value of y in the linear equation and then compare

-----> is not true
therefore
The ordered pair case C) is not a solution
case D) 
substitute the value of x and the value of y in the linear equation and then compare

-----> is not true
therefore
The ordered pair case D) is not a solution
Answer:

Step-by-step explanation:
In a right triangle there are 2 legs and a hypotenuse. The way you can tell if it's a right triangle is by finding the slope of both the legs. If their slopes are opposite reciprocals of each other, then they are perpendicular. By definition, perpendicular lines meet to create a right angle.
