Answer:
The value of the equation for x is
or 559.5.
Step-by-step explanation:
Consider the provided equation.

We need to solve the equation for x.
Use the distributive property: 


Add the like terms.

Isolate the variable as shown:




Hence, the value of the equation for x is
or 559.5.
For this case we have the following line:
x = 4
The first thing you should know is that the slope of the line is given by:
m = (y2-y1) / (x2-x1)
In this case:
x2 = x1
Thus,
The slope is:
m = (y2-y1) / (0)
m = infinity
Answer:
The slope of the line is:
m = infinity
