Fractions and Changing Fractions-Decimals or Decimals-Fractions Write each in decimal form 𝟏𝟐 𝟕 𝟏𝟑 𝟗 𝟒 𝟏𝟖 Write each in fraction form 8.75 4.6 3.3
Setting Windows Set the Window values so you can see the graph. Remember if you are going to use 2nd Calc 2,3,4, or 5 you have to see the point on the graph
Setting Tables Instead of solving with fractions we can set the table so the calculator does the work!

When given y = either in the problem or in the answers, use “Y =“! Testing Strategies When given y = either in the problem or in the answers, use “Y =“!
Testing Strategies substitute and use the calculator! 2) When given values for variables in the problem or in the answers, substitute and use the calculator!
x = 1, y = 24
