Question 1012412
slope-intercept form: 
y=mx+b
y=(1)x+(-2)
The slope is 1
The slope of the perpendicular line is the
negative inverse. Negative inverse of 1 is -1.
.
The equation will have the form:
y=(-1)x+b
Put in values of given point and solve for b:
-3=(-1)(2)+b
-3=-2+b
-1=b
Use this value of b in the equation:
y=(-1)x+(-1)
y=-x-1
.
ANSWER: Equation of the perpendicular line through (2,-3):
y=-x-1
.
