Answer:
y - 2 = -2 (x - 7)
Explanation:
first you need to find the slope. the slope formula is (y₂ - y₁) / (x₂ - x₁) and if you plug the numbers in [(6,4) as the ₁'s and (7,2) as the ₂'s], you will get (2 - 4) / (7 - 6) which is -2. the point slope form is y - y₁ = m (x - x₁). in your equation, it has half of it done using (7, 2), so we'll use that as the ₁. plug it in, and you get y - 2 = -2 (x - 7)
hope this helps!
