False
(-6,5) is not a solution to 7x = 5y + 9

Replace x with -6 and y with 5 to see why.
7(-6) = 5(5) + 9
-42 = 25 + 9
-42 = 34
This is not true.

I'm not even sure if this is what you were asking for?

If you want the line that is perpendicular to the given line and passes through the given point then:

Put the line in slope intercept form.
7x = 5y + 9
5y = 7x - 9
y = (7/5)x - 9

So the slope (m) of the line is 7/5 and the slope of a line perpendicular to this line is (-1/m) or -5/7

So the line is:
y = (-5/7)x + b

Put in (-6,5) to get the value of b
5 = 30/7 + b
b = 5 - 30/7 = 5/7

So the line is:
y = (-5/7)x + 5/7 or 7y = -5x + 5

x= -6
y=5

7(-6)=5(5)+9
-42=25+9
-42=34

This statement is false because if you take that order pair and you plug it in, you get at statement that says -42 equals 34, which is not true.

7(-6)=5(5)+9
-42=25+9
That point is not on the line, not that you asked that.
