Greatest common factor (GCF) of 7 and 15 is 1. We will now calculate the prime factors of 7 and 15, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 7 and 15.
Answer:
y=-2x+80
Step-by-step explanation:
40=(-2*20)+b
40=-40+b
80=b
y=(-2*20)+80
y=-40+80
y=40
