Answer:
2x
Step-by-step explanation:
we can use the Pythagorean Theorem to find the missing side (a):
a² + (2x)² = (8x)²
a² + 4x² = 64x²
a² = 60x²
a = √60x²
a = ·
·
This can be simplified to be 2x
The slope of the line is 2/3
Step-by-step explanation:
The slope of a line is the rate of change of the dependent variable (y) with respect to the rate of change of the independent variable (x). Mathematically,
where
is the increment of the y-variable
is the increment of the x-variable
Given two points of coordinates and
belonging to the line, the slope of the line can be calculated as
In this problem, the following two points belong to the line:
(3,3)
(-3,-1)
Therefore, the slope of the line is:
