    before u can graph this equation get the equation in standard form: y=mx+b

    first solve this equation y-3=2(x-4) y-3=2x-8 y=2x-5

    so -5 is the y value when x is 0 then the slope is m which is 2 so go up 2 points from -5 go left 1 because your slope is really 2/1 that's you next point then draw a line through both points

    No, no I don't. Putting different numbers in will give me different answers?

    as what @mayankdevnani just said is right if u plug a value of x in an equation u get a value of y for that x value if u get 2 of those points they both belong to one equation that u want to graph so its not wrong u can also look at previous answer which is a different method of graphing

    about what ? u have to graph the line, right ? find x and y intercepts, plot them, and just daw a staright line passing through them. To get x-intercept put y=0 in the equation to get y-intercept put x=0 in the equation i am too lazy to go through all the comments....
