what us the equation of the line shown in this graph (-4,1) (2'1)

Answer:
y=1
Step-by-step explanation:
we know that the equation of the line is:
y=mx+b
m= slope= (y2-y1)/(x2-x1)
we have two points giver from the graph:
point 1: (-4,1)
point 2: (2,1)
we to find the slope:
m=(1-1)/(2-(-4))
so we have m=0
we need to find "b"
using the point (2,1)
we have:
1=0x+b
so we have b=1
finally we have
y=0x+1
so y =1
