Plz mark as brainliest ! :D
The question isn't very clear to me but i'll try it out.

B=1+2
B=3
HOPE I HELPED!!!
Point slope is y-y1= m(x-x1) where m is slope and x1 and y1 are the known coordinates.
y-(-9)=-2(x-10)
y+9=-2(x-10)
Final answer: y+9=-2(x-10)
Y=mx+b
x=number of newspapers
37.5 earned for 5 newspapers
37.5=5m+b
earned 75 and deliverd 20 newpapers
75=20m+b
we have
37.5=5m+b and
75=20m+b
multiply first equaiton by -1 and add to other equaiton
-37.5=-5m-b
<u>75=20m+b +</u>
37.5=15m+0b
37.5=15m
divide both sides by 15
2.5=m
sub back to find b
75=2.5(20)+b
75=50+b
minsu 50 both sides
25=b
y=2.5x+25 is lnear funtion
