Question

How do you write the equation of a line in point slope form and slope intercept form given points (4, -2) (9, -8)?

Answer 1

`[slope](http://socratic.org/algebra/graphs-of-linear-equations-and-functions/slope): (y2 - y1)/(x1 + x2) =( (-8 -(- 2))/(9 - 4)) = -6/5`

equation: `y = (-6x)/5 + b`
