Plug in the 1/2 where the a’s are answer is -3
Paralell has same slope
y=mx+b
m=slope
y=1/2x+b
find b
(x,y)
(4,0)
x=4
y=0
0=1/2(4)+b
0=2+b
minus 2 both sides
-2=b
the equaiton is
y=1/2x-2
or
x-2y=4
Tax she will pay would be $2.04
A) 0.59 uses 2 sig figs
B) 100.6 uses 4 sig figs (the zeros in this case are significant)
C) 98.42 uses 4 sig figs
D) 1.045 uses 4 sig figs (the zero is between other sig figs so it's significant)
Every choice but choice A has 4 sig figs. So the answers are B, C, and D
