Answer:

Step-by-step explanation:
<em>y=mx+b</em>
<em>b is where the line touches the y-intercept</em>
<em>mx is the slope...rise over run (positive slope) OR fall over crawl (negative slope)</em>
<em />
b= 8
mx= -3/2
y= -3/2x+8
Answer:

Step-by-step explanation:
Given:
Two points are given
x = number of minutes
y = length of the lin
⇒ (0, 6)
⇒ (20, 17)
We need to find the equation that represents the relationship between x, y.
Solution:
Using slope formula to find the slope of the equation of the line.

Substitute
= (0, 6) and
= (20, 17) in above equation.

So, slope of the line 
Using point slope formula.
------------(1)
Where, m = slope of the line
Substitute
⇒ (0, 6) and
in equation 1.


Add 6 both side of the equation.


Therefore, the equation that represents the relationship between x and y is written as:

Answer:
x ≤ -3
Step-by-step explanation:
For solid lines you would do ≤ or ≥, then for shading on the right side you would need < or ≤
