Question

Complete the point slope equation of the line through (6,4) and (7,2)

Answer 1

y − 4 = -2 (x−6)

Explanation:

Point slope form: y - y₁ = m (x-x₁)

y₁: 4

x₁: -6

m: 2 - 4/7 - 1 = -2/1 = -2

Plug those into the point slope equation to get your final answer,

y − 4 = -2 (x−6)

Answer 2

Explanation:

Plot two points. Start at 6,4. Go up 1 to get to 7. The move left 2 to go from 4 to 2. So you have 1/-2 or - 1/2.
