Answer:

Step-by-step explanation:
Given
Horizontal Line

Required
Determine the equation
The equation is calculated using:

Where

Because the line is a horizontal line, then:

Substitute 0 for m and values for x1 and y1 in 



Subtract 2 from both sides


Hence, the equation is: 
Answer:
x > 10
Step-by-step explanation:
x-3 > 7
Add 3 to each side
x-3+3 > 7+3
x > 10
