Answer:
option B: y =2/3x+1
Step-by-step explanation:
First 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: (3,3)
point 2: (-3,-1)
we to find the slope:
m=(-1-3)/(-3-3)
m= -4/-6
m=2/3 = slope
Now we need to find "b"
using the point (3,3), we have:
3=(2/3)(3)+b
3=2+b
b=3-2
b=1
finally we have
y=(2/3)x+1 = option B
