Answer:
y=-3x+5
Step-by-step explanation: y=mx+b
to find slope (m) use the equation 
so
= -3
to find b
use y=mx+b
-1=-3(2)+b
-1=-6+b
5=b
Hope this helps :)

Answer:
$127.75
500 quarters equals $125.00 (500 x 0.25 = 125)
25 dimes equals $2.50 (25 x 0.10 = 2.50)
25 pennies equals $0.25 (25 x 0.01 = 0.25)
Answer:
g (-2) = 22
Step-by-step explanation:
Evaluate g( -2) if g(x) = x^2 – 4x + 10
g(-2) = (-2)^2 - 4(-2) + 10
g(-2) = 4 + 8 + 10
g (-2) = 22
