Answer:
We are calculating the Hypotenuse of a right triangle.
Step-by-step explanation:
Distance Formula: When working on a coordinate plane, you can always find the distance between two points (or the length of a line segment) by creating a right triangle and using the Pythagorean Theorem. Draw a right triangle such that the distance between the two points is the hypotenuse.
Hence, When you use the distance formula, you are calculating the length of the Hypotenuse of a right triangle.
We could also see from the figure attached.
Can anyone explain this one?
a. Solve the system by the linear combination method. Show all work carefully.
b. Check your answer.
a - 2b = 2
a - b = 6
