You can put this solution on YOUR website!
m=(3-12)/(2--4)
m=-9/6
m=-3/2
-------------------
y=mx+b
3=-3/2*2+b
3=-6/2+b
3=-3+b
b=6
-------------
y=-3/2x+6

how do you find the equation of the line that goes through the
two points P(-4, 12) and Q(2, 3) and then express your answer in slope-interceot form.
----------------
slope = (12-3)/(-4-2) = -9/6 = -3/2
---------------
Form: y = mx + b
Solve for "b":
3 = (-3/2)2 + b
b = 6
----
Eqution:
y = (-3/2)x + 6
