Question

find the equation of a line whose inclination is 30°and making an intercept- 3 on the y axis​

Answer 1

Answer:

given: Θ = 30° , y intercept = -3

to find the equation

Step-by-step explanation:

equation of line given angle and y intercept is,

y = m x + c => where m = tan Θ = slope and c = y intercept

m = tan 30° = 1/√3

=> y = 1/√3 x + (-3)

=> y = (1/√3) x - 3

=> y = (x + 3√3) / √3

=> √3 y = x + 3√3

=> x - √3 y + 3√3 = 0 Answer
