Answer:
y = 7 is the desired equation
Step-by-step explanation:
If the line is horizontal, then its slope is zero (0). If this horizontal line passes through (4, 7), then y = 7 is the desired equation.
Answer: X = 1
How to solve:
Add 8 to both sides of the equation
-7 +8 = 1
Answer:
See explanation
Step-by-step explanation:
Given triangle has its vertices at points A(-4,-2), B(1,3) and C(3,-2).
Find all sides lengths:

The longest side is AB.
By the Pythagorean theorem,

This is false statemnt, so this triangle is not right triangle.
