Answer:
y=-1/5 x +7/5
Step-by-step explanation:
First lets find the slope for line containing the two points (2,3) and (1,2)
[tex]m=\frac{3-(-2)}{(2-1)}\\[/tex]
m=5
Two lines are perpendicular between each other if m1*m2=-1
we have one slope m1=5, we obtain m2= -1/5
Next we need to eval the equation for lines y=mx+b, where m= -1/5 using the point P(-3,2)
2=-1/5 * -3 +b
From that we obtain that b= 2-3/5=7/5
So the equation for the desired line is:
y=-1/5 x +7/5
