Assuming you want to use fractions in your equation, let's use an example: 5/7 + 10/7Basically, you don't want it to divide the numbers first then add, because they are supposed to be fractions. Therefore you press the parentheses key and type: "5" "divide" "7" then the close parentheses sign. And you continue on, using the parentheses whenever you are symbolizing fractions.However, if you want to make your answer into a fraction.. it's a lot easier. Simply input whatever you are solving and then press enter. After wards, press the "MATH" key and enter when FRAC is highlighted. It should be #1. And there you have it, using fractions on TI-84 Plus Silver Edition :)
The question is not quite clear but one equation will be y = 3x+6 and the other equation will have a slope of minus 1/3
