You can put this solution on YOUR website! find an equation of the line through the givven point and perpendicular to the given line y=1/2x+3 and (-4,2)
**
Equation of a line: y=mx+b, m=slope, b=y-intercept
For given equation: y=1/2x+3
m=1/2
slope of perpendicular line=-2(negative reciprocal)
equation:
y=-2x+b
solve for b using coordinates of given point (-4,2)
2=-2*-4+b
b=-6
Equation of perpendicular line:
y=-2x-6
