Thank you for the opportunity to help you with your question!

Equation of line in slope intercept form is

y = mx + b

where m is the slope and b is the y-intercept.

The line which is perpendicular to f has y-intercept of -2.

Therefore, b = -2

So, equation of the perpendicular line is

y = mx - 2

Also its x-intercept is 1. So, substitute x = 1 and y = 0 in the equation.

0 = m*1 - 2

0 = m - 2

m = 2

So equation of the perpendicular line becomes 

y = 2x - 2

Since f is perpendicular to the above line,

slope of f = -1/m = -1/2

Also f passes through (-6, 9).

Now we can use the point slope form of line to find equation of f.

m is the slope of the line(slope of  f)

and  is a point on the line.

Here, m = -1/2 and  = (-6, 9) .

So, equation of line f is
