$color(blue)("Horizontal line " x = a$

$color(purple)("Vertical line " y = b$

Refer table above.

$"Equation of a line in" color(red)("Intercept Form") "is given by"$

$x / a + y / b = 1, " where a in x-intercept and b the y-intercept"$

For a horizontal line, y = 0 or y/b = 0 and the equation becomes,

$x / a = 1 " or " x = a$

Similarly, for a vertical line, x = 0 or x / a = 0 and the equation becomes,

$y / b = 1 " or " y = b$
