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....
