????????????? "solving the problem" ????????????? . . . wot problem...yu need tu figger out wot it be & tell us . . . me suspekt yu want tu make a strate line that go thru point=(3,-4) . . . How come yu didnt tell us wot yu want.???????? . . . then yu giv a thang....4x-2y=9....thats formula for a srate line . . sorta a kinda formula, but all warped . . . y=2x-4.5...this tell yu line hav slope=2 . . . thats half the problem . . . rite that down & paest it on yer forhed . . . yu need formula that look like y=2x+konst . . . It gotta go thru point=(3,-4) . . . projekt line from x=3 tu x=0...deltax=-3 . . . deltay=slope*deltax=2*(-3)=-6 . . . so at x=0, y=-4-6=-10 . . . anser: y=2x-10
