Draw a ramp and label its rise and run. Explain what is meant by the slope of the ramp.

In the ordered pair \((4,9),\) the \(x\) -coordinate is ______ $

Decide whether the following statement is true or false. Each point in a coordinate plane corresponds to an ordered pair of real numbers.

In a direct variation equation, how are the constant of variation and the slope related?

Describe a line that cannot be the graph of a linear function.

Graph the equation. State whether the two quantities have direct variation. If they have direct variation, find the constant of variation and the slope of the direct variation model. $$y=x$$

Describe a line that has no \(x\) -intercept.

Use a table of values to graph the equation. \(6 x-3 y=12\)
