Need help on graphing inequalities 18x-9y<2
just take that 18x-9y=2... draw the line, check either sides of the the graph wherever you got this function true will be your solution set... samjhi?
But what are the points in the graph where they supposed to be
OKAY , divide the whole equation by 2 , so that RHS has 1 , u get 18x/2 - 9y/2 = 1
its upto your choice.. we just have to check it on either side
9x - 9/2y = 1 plug in values of x and find the value of y , plot the graph
oh , wait 9x - 9/2y < 1 now whatever is x & y's coefficient , make it 1 , by dividing for x , it is 9 , for y it is 9/2 , put them on x & y axis respectively
draw a dotted line through the points , shade the region away from zero as the inequality is greater than 1
