### Making t chart

1. 1. Graphing Using a T-chart<br />
2. 2. First Draw a T-chart<br />A t-chart is used to keep the work organized. <br />
3. 3. Y = 3X + 7<br />X<br />Equation goes here<br />X-values here<br />First Draw a T-chart<br />
4. 4. Choose 3 x-values<br />It is good to pick at least one negative number a positive number and zero.<br />Let X = -2, 0, 2<br />You can pick any x-values that you want. There is not a wrong answer for this part. If your x-values are large, they will take more room to graph.<br />
5. 5. Y = 3X + 7<br />X<br />3(-2) + 7<br /> -2 0 2<br /> 3(0) + 7<br />3(2) + 7 <br />Place each x-value into the equation<br />
6. 6. Y = 3X + 7<br />X<br />3(-2) + 7 = 1<br /> -2 0 2<br />3(0) + 7 = 7<br />3(2) + 7 = 13<br />Compute the y-values<br />
7. 7. Y = 3X + 7<br />X<br />3(-2) + 7 = 1<br /> -2 0 2<br />3(0) + 7 = 7<br />3(2) + 7 = 13<br />Match the x-value and the y-values<br />X - values<br />Y - values<br />
8. 8. Locate the Ordered Pairs<br />( -2 , 1 )<br />( 0 , 7 )<br />( 2 , 13 ) <br />Plot these points on your graph.<br />
9. 9. Graph on Coordinate Grid<br />Notice our graph only goes to 10 ,but our largest value is 13 on the y-axis.<br />(-2,1)<br />(0,7)<br />(2,13)<br />
10. 10. Graph on Coordinate Grid<br />Since my graph was not long enough, I chose to improvise and made my point extend off the grid. <br />(-2,1)<br />(0,7)<br />(2,13)<br />Another solution would have been to count by two’s on the graph.<br />
11. 11. Connect Points<br />
12. 12. Congratulations!<br />
