The line x − y = 2 is on a coordinate plane and contains EF, which is one side of square EFGH. What is the slope of the line tha
Alborosie

Answer:

The slope of FG is -1

Step-by-step explanation:

Given

Square EFGH

EF: x - y = 2

Required

Determine the slope of FG

First, we calculate the slope of EF

x - y = 2

Make y the subject

-y = 2 - x

y = x -2

The general equation has the form: y = mx + b

Where

m = slope

Compare y = mx + b to y = x -2

m = 1

<em>From the name of the square EFGH, we can conclude that EF and FG are perpendicular</em>

<em />

The relationship between perpendicular lines is:

m_2 = -\frac{1}{m_1}

Where

m_1 = m = 1 -- Slope of EF

and

m2 = slope of FG

Substitute 1 for m1 in m_2 = -\frac{1}{m_1}

m_2 = -\frac{1}{1}

m_2 = -1\\

<em>Hence, the slope of FG is -1</em>
