Find the equation of each line.
Slope = change in y over the change in x.
Solid line =
(0,2) (4,0)
Slope = (0-2):(4-0) = -2/4 = -1/2
Y intercept is where the line crosses the y axis when x is 0, which is at 2
Line = y = -1/2x + 2
Dotted line=
(0,-3) (2,1)
Slope = (1- -3)/ (2-0) = 4/2 = 2
Y intercept is -3
Line = y = 2x-3
A solid line means it is included in the answer a dotted line means it is not included. The colored are is above the lines.
The inequalities are.
Y >= -1/2x+ 2
Y > 2x-3
