# Steve starts with $350 and spends$35 a week. Chelsea starts with $20 and saves$20 a week. How do you use x for time and y for savings and complete the equations that represent these situations?

Chelsea's graph would start at $\left(0 , 20\right)$ and would increase by $20 each week, so the equation would be $y = 20 x + 20$Steve's graph would start at $\left(0 , 350\right)$and decrease by $35 each week, so the equation would be
$y = 350 - 35 x$
