Write the slopeintercept form of an equation of the line that passes through the given point and is perpendicular to the graph of each equation.
1.(2,2),y=1/3x+9
2.(4,3),4x+y=7
3.(4,1),4x+7y=6
4.(6,5),4x+3y=6
These are the answer I came up with, could you review them? Thanks
1.y=3/1x+4
2.y=1/4x2
3.y=7/4x+8
4.y=3/4x1/2

all correct
