a) The slope is
[tex]\frac{1350-1500}{2-0}=-75[/tex]
This represents that every day, there are $75 taken out of the bank account.
b) Point-slope: [tex]y-1350=-75(x-2)[/tex]
Slope-intercept: [tex]y=-75x+1500[/tex]
Standard form, [tex]75x+y=1500[/tex]
c) [tex]g(x)=-75x+1500[/tex]
d) When x=5, [tex]g(5)=-75(5)+1500=\$1125[/tex].
