write an equation in standard form of the line passing through these points.
(-2,0) and (2,-3)
------------------
slope = (-3-0)/(2--2) = -3/4
--------------------------------
Form of the equation: y = mx + b
You now know x,y, and m; solve for b as follows:
-3 = (-3/4)*2+b
-3 = (-3/2) + b
b = (-3/2)
--------------------
EQUATION:
y = (-3/4)x - (3/2)
----------------------
Write it in standard form:
Multiply thru by 4 to get:
4y = -3x - 6
Rearrange:
3x+4y = -6
-----------------

Stan H.
