Question

What is an equation of the line that passes through the point (3,5) and is parallel to the x-axis? A) x = 3 B) y = 5 C) x = 5 D) y = 3

Answer 1

$\begin{gathered} \text{ Since it is parallel to the x-axis, it has the shape} \\ x=a\text{ for some number a},\text{ } \\ \text{Now, we know that x passes through (3,5) so a=3} \\ \\ we\text{ get } \\ x=3 \end{gathered}$
