Answer:
Y= -1/2x + 1
Step-by-step explanation:
The equation for a line is Y=Mx+B
M stands for the Slope.
  -Slope is rise/run. So, for this graph the line "rises" 1 point and "runs" left 2 points until meeting the line again. This slope is negative because it "runs" to the left. 
B stands for the Y-Intercept
 -The Y-intercept is the point at which the line crosses the Y axis. For this example, the line crosses the Y-intercept at (0,1).

Answer:
p = 2a-22
a= p-20 
these will help you find the actual value 
Step-by-step explanation:
this is not for the actual value 
pierre = p

p = a+20
p-20 = a
p+22 = 2a
p = 2a-22
