Slope: -9
Perpendicular slope: (-9)/1 ---> -(-1/9) = 1/9
So m = 1/9
-------------------------------------------------------
The x-intercept is -1, so (-1,0) is a point on the line. So x = -1 and y = 0
y = mx+b
y = (1/9)x+b
0 = (1/9)(-1)+b
0 = -1/9+b
0 + 1/9 = b
1/9 = b
b = 1/9
So the equation of the line is
