Directions – Identify the key components, then write a system of inequalities for the graph
blue 0,4 and 3,1
red -1,0 and 0,2
Line 1 (red)
b= blank
m=blank
inequality:blank
For Line 1 (red):
b = y-intercept = 0
m = slope = (2-0)/(0-(-1)) = 2/1 = 2
inequality: y ≤ 2x + 0 or y ≤ 2x
Line 2 (blue)
b = y-intercept = 4
m = slope = (1-4)/(3-0) = -3/3 = -1
inequality: y ≥ -x + 4 or y ≥ -x + 4
Line 2 (blue)
b=
m=

For Line 2 (blue):
b = y-intercept = 4
m = slope = (1-4)/(3-0) = -3/3 = -1
inequality: y ≥ -x + 4
