Answer:
Step-by-step explanation:
The interval [4, ∞) all real numbers 4 and greater, whereas the interval (4,∞) not includes the endpoint 4.
Y = mx + b
y = 3/5(x) + b
-4 = 3/5(2) + b
-4 = -2.4 + b
b = -4 + 2.4
b = -1.6 (-8/5)
y = 3/5x - 8/5.
X=-4 x=0 x=5
5-4-12=-4-7 5+0-12=0-7 5+5-12=5-7
-11=-11 -7=-7 -2=-2
