I'm having trouble with graphs and tables and equations.. i'm in math 1 and need filling out the table (y=3x-1) i have to graph it after and i really need getting the y output

Really simple. Just input several x values into the equation t get the y values (output) for example if x=1 then y= 3(1) -1 which is 2. So one of your coordinates would be (1,2). 

Let's say we want to find when x=5. Then y would be y=3(5)-1 which would be 14. Our next coordinate to graph would be (5,14)

Hope I helped!
