You can put this solution on YOUR website! Write the equation of the line that passes through the points (3, 4) and (–3, –8) in point-slope form and explain each step you took to get to your answer.
**
point-slope formula: (y1-y2)=m(x1-x2)
find slope,m=∆y/∆x=change in y/change in x
using coordinates of given points,
m=(4-(-8))/(3-(-3))
=(4+8)/(3+3)
=12/6
m=2
apply point-slope formula using any one of the given points(3,4), and slope m=2
(y-4)=2(x-3)
