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

Explanation:

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#
