Answer:
2x - y - 7 = 0
Step-by-step explanation:
Since the slope of parallel line are same.
So, we can easily use formula,
y - y₁ = m ( x ₋ x₁)
where, (x₁, y₁) = (8, 9)
and m is a slope of line passing through (x₁, y₁).
and since the slope of parallel lines are same, so here we use slope of parallel line for calculation.
and, Slope = m = ![\dfrac{y_{b}-y_{a}}{x_{b}-x_{a}}](https://tex.z-dn.net/?f=%5Cdfrac%7By_%7Bb%7D-y_%7Ba%7D%7D%7Bx_%7Bb%7D-x_%7Ba%7D%7D)
here, (xₐ, yₐ) = (2, 7)
and, ![(y_{a},y_{b}) = (1, 5 )](https://tex.z-dn.net/?f=%28y_%7Ba%7D%2Cy_%7Bb%7D%29%20%3D%20%281%2C%205%20%29)
⇒ m = ![\dfrac{5-7}{1-2}](https://tex.z-dn.net/?f=%5Cdfrac%7B5-7%7D%7B1-2%7D)
⇒ m = 2
Putting all values above formula. We get,
y - 9 = 2 ( x ₋ 8)
⇒ y - 9 = 2x - 16
⇒ 2x - y - 7 = 0
which is required equation.
