Answer:
y = 3x-1
Third option is correct.
Step-by-step explanation:
From the given graph, we have
y -intercept = -1
And the line passes through the point (1,2)
The slope intercept form of the line is y =mx +b.
where, m is slope and b is y-intercept
Here, b = -1
Hence, the equation is in the form y = mx -1
Now,line passes through the point (1,2)
Substitute x = 1, y = 2 in the equation to find m
2 = 1m-1
3 = m
m = 3
Hence, the equation of the line is y = 3x-1
