Answer:
since the equation of the line is perpendicular to y (m2= -1/m1)
using the formula y=mx+c
m1=1/9
since m2 = -1/m1
m2= -1/1/9
m2 = -9
The other line passing through (3,7) has a slope of -9
using the formula
y-y1 = m(x-x1)
y-7= -9(x-3)
y-7= -9x+27
y= -9x +27+7
y= -9x +34(equation of the line)
