Directions – Identify the key components, then write a system of inequalities for the graph

Question

blue 0,4 and 3,1
red -1,0 and 0,2

Line 1 (red)
b= blank
m=blank
inequality:blank

Answer 1

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

Answer 2

Line 2 (blue)

b=
m=
inequality=

Answer 3

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