Question

find the equations of line which contain the points (4,1) & X intercept is twice its Y intercept


Fast​

Answer 1

Answer:

let X-intercept be 'a' & Y-intercept be 'b'.

so , given a=2b.

⇒X/a+Y/b=1 [intercept equation]

⇒X/2b+Y/b=1

since the line passes through (2,1).

⇒b=2

⇒a=4

∴the equation is , X+2Y=4
