Answer:
option B
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 given from the graph:
point 1: (0,2)
point 2: (2,-1)
we to find the slope:
m=(-1-2)/(2-0)
m= -3/2= slope
we need to find "b"
using the point (0,2), we have:
2=0x+b
so we have b=2
finally we have
y=(-3/2)x+2 = option B
