java - solving all y values for equations of the format y = mx+c -


i creating program in enter equation in format of y = mx+c

it give y values -2 +2.

an example of user may enter y = 2x+5.

how solve this? want input integer values x don't know or how start.

if want input integers value of x can use following method below... method allows chose value of gradient , y-intercept.

you use method: 

    public static void rangecalculator(int startpoint, int endpoint){      scanner input = new scanner(system.in);     system.out.print("enter gradient:");     double gradient = input.nextdouble();     system.out.print("\nenter intercept:");     double intercept = input.nextdouble();      for(int i=startpoint; i<=endpoint; i++){         system.out.println("y="+gradient+"x + " +intercept+"\t" + "input:"+i + " output:" + (gradient*i + intercept));     } }
