I.C 10-5-09 Big idea-Negative numbers help us to model many real world situations Essential question- How do we multiply and divide integers


 * A On paper make a table of x and y values for the equation y=3x+2.**
 * x || y1 ||
 * 9 || 29 ||
 * 10 || 32 ||
 * 11 ||  || 35 ||
 * 12 || 38 ||
 * 13 || 41 ||
 * 14 || 44 ||
 * 15 || 47 ||


 * B On grid paper, sketch a graph of y=3x+2.

C Enter the equation y=3x+2 into your graphing calculator, and press graph. Make a sketch of the graph you see. How does this graph compare to the graph you drew by hand?**

The graph i drew by hand was almost the almost the same but a little wider than the actual graph on the graphing calculator.


 * D 1 Make a sketch of the graph you see.**

Ans- This graph looks like the part of the graph I drew in part b. It is part of the first quadrant. **3 How does this graph compare with the graph you made with your calculator in part c?** Ans- It is part of the same graph I drew in part c. It is the thing that gives the coordinates to the calculator for the line to be drawn on the calculator. **E On paper, make a table of the x and y values for the equation y=2x.**
 * 2 How does this graph compare to the graph you saw in part b?**
 * 4 Explain what you think each entry on the window setting 1 screen means.**
 * x || y1 ||
 * -9 || -18 ||
 * -8 || -16 ||
 * -7 || -14 ||
 * -6 || -12 ||
 * -5 || -10 ||
 * -4 || -8 ||
 * -3 || -6 ||


 * F On grid paper, sketch a graph of y=2x.

G Enter the equation y=2x into your calculator and press graph. Make a sketch of the graph you see. H 1 Make a sketch of the graph you see.

2 How does the graph compare with the graph you drew in part F?** //The line on the graph is abit more tilted than the one i drew by hand// Its abit like the graph in part f. Its abit more tilted. I think it is the thing that give the calculator the coordinates to draw the lines on the graph.
 * 3 How does compare this graph compare with the graph you made with your calculator in part G?**
 * 4 Explain what you think each entry on the window settings 2 screen means.**
