Question

Find the equation of the line passing through the given points. Use function notation to write the equation, (-2,8) and (-6,20)

Answer 1

First you gotta find the slope

`(20 - 8)/( - 6 - ( - 2)) = (12)/( - 4) = - 3`
Then you can put it into point slope form using either of the points

`y - 20 = - 3(x + 6) \\ y - 20 = - 3x - 18 \\ y = - 3x + 2`
