Find the distance between the x-intercept and the y-intercept of the graph of the equation 3x - 6y = 18.
y int = 3(0) - 6y = 18 ⇒ y = -3
x int = 3x - 6(0) = 18 ⇒ x = 6
We can form a right triangle with legs of 3 and 6
The distance between the two intercepts is the hypotenuse = sqrt [6^2 + 3^2] = sqrt (45) =3 sqrt (5)
