%28x-7%29%28y%2B9%29=1
To find the x intercept, set y=0.
%28x-7%29%28y%2B9%29=1
%28x-7%29%280%2B9%29=1
%28x-7%29%289%29=1
x-7=1%2F9
x=7%2B1%2F9
x=63%2F9%2B1%2F9
highlight%28x=64%2F9%29
To find the y intercept, set x=0.
%28x-7%29%28y%2B9%29=1
%280-7%29%28y%2B9%29=1
%28-7%29%28y%2B9%29=1
%28y%2B9%29=-1%2F7
y=-1%2F7-9
y=-1%2F7-63%2F7
highlight%28y=-64%2F7%29
