The graph of part of linear function g is shown on the grid. Which inequality best represents the domain of the part shown?

Researchers in Antarctica discovered a warm sea current under a glacier that is causing the glacier to melt. The ice shelf of the glacier had a thickness of approximately 450 m when it was first discovered. The thickness of the ice shelf is decreasing at an average rate of 0.06 m per day. Which function can be used to find the thickness of the ice shelf in meters x days since the discovery?

The table represents some points on the graph of a linear function.

Which equation represents the same relationship?

The value of y is directly proportional to the value of x. If y = 35 when x = 140, what is the value of y when x = 70?

What is the equation of the line that passes through the point (-2, 7) and has a slope of zero?

• x = 7

• y = -2

• x = -2

• y = 7

A student is ordering a flower arrangement. She can choose any combination of roses and carnations for her flower arrangement, and she does not want to spend more than $30.
