Answer:
y = 4x + 5
Step-by-step explanation:
Take any two points
(0 , 5) & (2 , 13)
Slope =
m = 4 & (0 , 5)
y - y1 = m(x-x1)
y - 5 = 4(x - 0)
y - 5 = 4x
y = 4x + 5
Y-5=1/2(x-2) slope intercept form

The package weighs 30 ounces.
Step-by-step explanation:
Mailbox Plus charges;
Charges per ounce = $0.25

x be the number of ounces.
M(x)=5+0.25x
United packges charges;
Charges per ounce = $0.35
U(x) = 2+0.35x
