Question

Complete point slope form equation ( -1,6) and (1,5)

Answer 1

y - 6 = -1/2 (x + 1)

Explanation:

Point-slope equation:

y − y₁ = m(x − x₁)

m is the slope

We need to only find m

m = y₂ - y₁ / x₂ - x₁

m = 5 - 6 / 1 - (-1)

m = -1 / 1 + 1

m = -1/2

We know that,

x₁ = -1

y₁ = 6

m = -1/2

So substitute.

y - 6 = -1/2 (x - (-1))

y - 6 = -1/2 (x + 1)
