Question
What happens to a line when the y-intercept is changed? Check all that apply.A.As the y-intercept increases, the graph of the line gets steeper.B.As the y-intercept increases, the graph of the line shifts up.C.As the y-intercept decreases, the graph of the line shifts left.D.As the y-intercept decreases, the graph of the line shifts down.E.As the y-intercept increases, the graph of the line shifts right.
Solution
The correct answers are:
B. As the y-intercept increases, the graph of the line shifts up. D. As the y-intercept decreases, the graph of the line shifts down.
The y-intercept of a line is the point at which the line crosses the y-axis. Changing the y-intercept does not affect the slope of the line (how steep the line is), but it does change the position of the line on the graph. If the y-intercept increases, the line shifts up. If the y-intercept decreases, the line shifts down. The y-intercept does not affect whether the line shifts left or right.

Suppose you have $10 to buy either onions or breath mints. Onions cost $0.50 each, and breath mints cost $1.00. On a graph, onions are on the y-axis and breath mints are on the x-axis.
