Victor was trying to beat his old score of 582 points in a video game. if he scores exactly 17 points each rounds would he need to play to beat his old

While you were copying the question, you jumped from one "round" to the next one, and you left out the part that says " , then how many round" .  (We also know that you didn't proof-read your question before you posted it, but that problem belongs in the <English> category, not in <Math>.)

582 / 17 = 34.235

If he scores exactly 17 points each round, then after 34 rounds he has 578 points.  That's close, but not quite enough.  He has to play one more round.

All together . . . 35 rounds.  Then he has  595 points.  He beat his old score, so he can quit now and go do his math homework.  He has become a true Victor !

17x34= 578 17x35= 595 So 35 rounds

The answer will be y=-5+0 because the slope is -5 and the it has to go through y-axis 0
