MCQ
Identify the equation of a straight line.
  • A
    $\text{y}=2\text{x}^2$
  • B
    $\text{x}^2+\text{y}^2=\text{a}$
  • $\frac{\text{x}}{\text{a}}+\frac{\text{x}}{\text{b}}=1$
  • D
    $\frac{\text{x}^2}{\text{a}^2}+\frac{\text{x}^2}{\text{b}^2}=1$

Answer

Correct option: C.
$\frac{\text{x}}{\text{a}}+\frac{\text{x}}{\text{b}}=1$
 A straight line is a figure formed when two points $ A (x_1, y_1)$ and $B (x_2, y_2)$ are connected with minimum distance between them, and both the ends extended to
infinity. The standard form of a linear equation with variables $x$ and $y$ is:
$ax + by = c,$ where $a, b, c$ are constants and $x, y$ are variables.
