Answer:
y= -3x+14
Step-by-step explanation:
To get the slope of the perpendicular line, get the negative reciprocal of the slope
if m=1/3, the slope of the perpendicular line is -3
Substitute the coordinates into the equation of the perpendicular line with the new slope and solve for b
2=4(-3) +b
2=-12+b
Add 12 to both sides
b=14
So, if m=-3 and b= 14 the line's equation is y= -3x+14
