Lesson 13: Interpreting Points on a Coordinate Plane | Unit 7: Rational Numbers

At 9 a.m., it was below freezing. In what quadrant would this point be plotted?

At 11 a.m., it was $$10^\circ {C}$$ . In what quadrant would this point be plotted?

The $$x$$ -axis represents the number of hours before or after noon, and the $$y$$ -axis represents the temperature in degrees Celsius. In which quadrant should a point be plotted if the time is 3 hours after noon and the temperature is -5 degrees Celsius?

The $$x$$ -axis represents the number of hours before or after noon, and the $$y$$ -axis represents the temperature in degrees Celsius. What does the point $$(0, 0)$$ represent in this context?

Here are some bank transactions from a bank account last week. Which days' transactions represent negative values?

What scale would you use on the coordinate plane to plot the set of points $$(1, -6)$$ , $$(-7, -8)$$ , $$(-3, 7)$$ , $$(0, 9)$$ ? What value would you assign to each unit of the grid?

What value would you assign to each unit of the grid to plot the set of points $$(-20, -30)$$ , $$(-40, 10)$$ , $$(20, -10)$$ , $$(5, -20)$$ on the coordinate plane?

What value would you assign to each unit of the grid to plot the set of points $$(\frac {{-}1}{3},-1), (\frac{2}{3}, -1 \frac13), (\frac {{-}4}{3},\frac23), (\frac16, 0)$$ on the coordinate plane?
