Question

a lake near the arctic circle is covered by a 2 - meter - thick sheet of ice during the cold winter months. when spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. after 3 weeks, the sheet is only 1.25 meters thick. let y represent the ice sheets thickness (in meters) after x weeks. which of the following information about the graph of the relationship is given? choose 1 answer: a slope and x - intercept b slope and y - intercept c slope and a point that is not an intercept d x - intercept and y - intercept e y - intercept and a point that is not an intercept f two points that are not intercepts

Explanation:

• The \(y\)-intercept: When \(x = 0\) (at the start, before any weeks have passed), \(y=2\) meters. So the \(y\)-intercept is \((0,2)\).
• A non - intercept point: When \(x = 3\) weeks, \(y = 1.25\) meters. So the point \((3,1.25)\) is given and it is not an intercept (since \(x

eq0\) and \(y
eq0\)).

Answer:

E. \(y\)-intercept and a point that is not an intercept
