Answer:
y=-0.5x+3
Explanation:
14x-7y=4
7y=14x-4
y=2x-4/7
m1=2
We search for a line y=m2x+b2
m1*m2=-1 (because this line is perpendicular for the line which we have)
So 2m2=-1
m2=-0.5
Then If the point (-2,4) belongs to the searched line use its coordinates for the line y=m2x+b2
4= (-0.5) (-2)+b2
b2=3
y=-0.5x+3
