For x=20 years
substitute in the equation

Answer:
no im sorry
its bc you a phony :)
Step-by-step explanation:
hope you understand
Answer:
y = 3x - 17
Step-by-step explanation:
Parallel lines have the same slope so the equation would be y = 3x + b
plugging in the points you get -2 = 3(5) + b
this is -17 = b
Answer:
b
Step-by-step explanation:
b= luck
