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
