Answer:
- The Fire Department and the School
- The Fire Department and the Hospital.
Step-by-step explanation:
On the matrix, a 1 represent the existence of a street between two buildings while a 0 indicates the absence of a street between any two building.
Let:
- F represent the Fire department
- S represent the School
- H represent the Hospital
- A represent the Apartment Building.
The heading by the side of the matrix is the <em>ith</em> entry while the headings on top is the <em>jth</em> entry. Movement is from ith position to jth position.
From the given matrix, the directed graph is presented in the attachment below.
From the graph, the following buildings have two-way streets between them.
- The Fire Department and the School
- The Fire Department and the Hospital.

The equation of the line that passes through the point (-6,-3) and has a slope of 0 is y = -3
The line is passing through the point = (-6,-3)
The slope of the line = 0
The point slope form is
Substitute the values in the equation
(y-(-3)) = 0×(x-(-6))
We have to convert this equation the slope intercept form
Slope intercept form is
y = mx + b
Where m is the slope of the line
b is the y intercept
(y-(-3)) = 0×(x-(-6))
y+3 = 0×(x+6)
y+3 = 0
y = -3
Hence, the equation of the line that passes through the point (-6,-3) and has a slope of 0 is y = -3.
