Answer:
D. y=2x+2
Step-by-step explanation:
the equation of a line is given by:
y=mx+b
m is the slope and b is the y-axis interception (0,b)
hence using the graph we can see that b=2, m can be obtain using 2 points one would be (0,2) and the other would be (-1,0)
m=(0-2)/(-1-0)= 2
so we have:
y= 2x+2
