Answer:
(5,4) & (8,-10)
Step-by-step explanation:
First step:
You can use any number you want for b (I used 4)
Make x=0
Make y=0
Subtract 4 from both sides
Divide both sides by 
Second step:
In order to make a line perpendicular to another the slope of the second line will be the negative inverse of the first line. So 
will be 
for the second line.
Then you just need to repeat the process in first step to get the intercepts. (Again I used a random number like -10 for b)
Well we do know that 7x9 = 63
I only know 1 way but I dont know if it is Distributive
