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
$\frac{20 - 8}{ - 6 - ( - 2)} = \frac{12}{ - 4} = - 3$
Then you can put it into point slope form using either of the points
$y - 20 = - 3(x + 6) \\ y - 20 = - 3x - 18 \\ y = - 3x + 2$
