Write an Equation Perpendicular to an Equation Through a Point
==Steps:==
- Remember, opposite reciprocal=flip sign and numbers
Example:
y=-2x+4 through (-3, -2)
y=1/2x+b
- ==Opposite reciprocal==
-2=1/2(-3/1)+b
-2= -3/2+b
+3/2 +3/2
-1/2=b
y=1/2x-1/2
==Steps:==
Example:
y=-2x+4 through (-3, -2)
y=1/2x+b
-2=1/2(-3/1)+b
-2= -3/2+b
+3/2 +3/2
-1/2=b
y=1/2x-1/2
