Question -
Answer -
(i) (0, 0) and (2, -2)
Given:
(x1, y1)= (0, 0), (x2, y2) = (2, -2)
The equation of theline passing through the two points (0, 0) and (2, −2) is
By using the formula,
y = – x
∴ The equation of lineis y = -x
(ii) (a, b) and (a + c sinα, b + c cos α)
Given:
(x1, y1)= (a, b), (x2, y2) = (a + c sin α, b + c cos α)
So, the equation ofthe line passing through the two points (0, 0) and (2, −2) is
By using the formula,
y – b = cot α (x – a)
∴ The equation of lineis y – b = cot α (x – a)
