Concept:
Straight Lines:
- The general equation of a straight line is y = mx + c.
- If two lines are parallel, then their slopes are equal.
Calculation:
Let the equation of the required line be y = mx + c.
Since this line pass through (5, 8), we must have:
⇒ 8 = 5m + c ---(1)
Also, the slope of the x-axis is 0 and, therefore, the slope of the required line should also be 0.
i.e. m = 0.
Substituting this value of m in equation (1), we get:
c = 8.
∴ The required equation of the line is:
y = 0(x) + 8
⇒ y = 8.

In point slope form, the equation is
y - y1 = m(x - x1)
m = 5
x1 = 5
y1 = -8
Plug in the numbers.
