Answer:
a = 3
Step-by-step explanation:
The given equation, x = 3 represents the standard form of vertical lines with an undefined slope, x = a.
Vertical lines have an undefined slope because the points on the graph have no horizontal change. Thus, when you choose two points on the graph and solve for the slope using the slope formula, m = (y₂ - y₁)/(x₂ - x₁), the denominator will result in a difference of zero. Additionally, division by zero is an undefined operation.
Therefore, the value of "a" in the equation, x = 3, is 3.
