You didn't specify how big the festival is. so i can't find the answer.....but i will try first let's devide 10,000 by 0.9 to see how many square metres we need, to fit 10,000 people 10,000÷0.9=11,111 square meters we need atleast 11,111 meters of land for a safe festival
The slope intercept form would be y= -1/2x + 1 and to get it into standard form all you have to do is move the -1/2 x to the other side, making it 1/2x + y = 1
