Answer:
The y-intercept is y = 2
Step-by-step explanation:
A linear function has the following format:

In which m is the slope and b is the y-intercept, which is the value of y when x = 0.
We are given these three points:
(-28, -54)
(-21, -40)
(-14, -26)
We use two of them to build a system, to find values for m and b.
(-28, -54)
This means that when 
So




(-21, -40)
This means that when 
So








The y-intercept is y = 2

Answer:
x ≥14
Closed circle at 14 line to the right
x≤3
closed circle at 3 line to the left
Step-by-step explanation:
(x-4)/5 ≥2
Multiply by 5
(x-4 )/5 *5 ≥2 *5
x-4 ≥10
Add 4 to each side
x-4+4≥10+4
x ≥14
Closed circle at 14 line to the right
3x-4 ≤5
Add 4 to each side
3x-4 +4≤5+4
3x ≤9
Divide by 3
3x/3 ≤9/3
x≤3
closed circle at 3 line to the left
