Answer :
[tex]x-weeks\\y-total\ money\\2x-saving\ every\ week\\\\\boxed{y=2x+20}[/tex]
so at first you have 20
so
y= money saved so
so each week times 2 +20 =total because
you started with 20 then
x weeks times 2 gives you how much you earned so
y=2x+20
slope=2
(slope intercept form=y=mx+b where m=slope)
so
y= money saved so
so each week times 2 +20 =total because
you started with 20 then
x weeks times 2 gives you how much you earned so
y=2x+20
slope=2
(slope intercept form=y=mx+b where m=slope)
