y < 4x + 5
y > -3x+2
The red line represents y < 4x + 5
The blue line represents y > -3x + 2
The area with the two colors is the area of the solutions
To draw the first line
put x = -1 and 1
y = 4(-1) + 5 = -4 + 5 = 1
The point is (-1, 1)
y = 4(1) + 5 = 4 + 5 = 9
the point is (1, 9)
Draw the line joining these two points
To draw the 2nd line
Put x = -1 and 1
y = -3(-1) + 2 = 3 + 2 = 5
The point is (-1, 5)
y = -3(1) + 2
y = -3 + 2 = -1
The point is (1, -1)
Draw the line joining these two points
Remember the lines must be dashed not solid
For the first line because the sign of inequality is <
shad the area under the line
For the second line because the sig
