Answer:
- The relationship between the number of months after the first year and the amount on the remaining card is linear and inverse ( Which meant that ,when the number of months after the first year increases , the amount on the remaining car decreases , in a linear way ) .
- The Independent variable is the <u>numbers of months after the first year .</u>
- The Dependent variable is the<u> </u><u>amount on the remaining card , Bcoz this amount depends on the time it has passed since the first year , ( which is our independent variable!).</u>
- <u>If </u><u>we </u><u>call </u><u>"</u><u>Y"</u><u> </u><u>our </u><u>dependent</u><u> </u><u>variables</u><u> </u><u>and </u><u>"</u><u>X"</u><u> </u><u>our </u><u>Independent</u><u> </u><u>variable</u><u> </u><u>,</u><u> </u><u>This </u><u>relationship</u><u> </u><u>can </u><u>be </u><u>written</u><u> </u><u>as </u><u>Y=</u><u> </u><u>2</u><u>5</u><u> </u><u>-</u><u> </u><u>2</u><u>.</u><u>5</u><u>x</u><u>.</u>
- <u>If </u><u>no </u><u>months </u><u>had </u><u>passed </u><u>since </u><u>the </u><u>first</u><u> </u><u>year,</u><u> </u><u>then </u><u>x=</u><u> </u><u>0</u><u> </u><u>and </u><u>the </u><u>amount</u><u> </u><u>in </u><u>the </u><u>card </u><u>equals </u><u>$</u><u>2</u><u>5</u><u> </u><u>,</u><u> </u><u>While </u><u>if </u><u>one </u><u>month </u><u>has </u><u>passed </u><u>since </u><u>the </u><u>first </u><u>year </u><u>x=</u><u> </u><u>1</u><u> </u><u>and </u><u>y=</u><u> </u><u>2</u><u>2</u><u>.</u><u>5</u><u> </u><u>(</u><u> </u><u>The </u><u>amount</u><u> </u><u>in </u><u>the </u><u>card </u><u>in </u><u>this </u><u>case </u><u>is </u><u>$</u><u>2</u><u>2</u><u>.</u><u>5</u><u> </u><u>.</u>
