Inequalities on Graphs

1234
Question 4

The graphs of the straight lines with equations y=2x+1y = 2x + 1y=2x+1 and 3y+2x=123y + 2x = 123y+2x=12 have been drawn on the grid.

A coordinate grid with x and y axes ranging from -6 to 6. Two straight lines are plotted: y = 2x + 1 and 3y + 2x = 12.

x x\,x and y y\,y are both integers.

Mark with a cross (×\times×) all of the points that satisfies all the inequalities

y<2x+1 y < 2x + 1 y<2x+1 3y+2x<12 3y + 2x < 12 3y+2x<12 y>1 y > 1 y>1
