Is there supposed to be a attached file? Or are you confused about the topic in general. I can help if need be. I’ll start off with saying that a system of equation is two equations that either have infinite, no, or one solution. This solution makes x true for both equations. x will be the same value for each equation.
For this item, we let x be the number of hours she works out and y be the total number of bananas that she will be eating after the workout. The expression that best described the given above is,
y = 5 + 2x
5 is given as the y-intercept because of the initial condition.
