The calculated equation of the line is d. y - 2 = -3(x - 1)
How to determine the equation of the line
From the question, we have the following parameters that can be used in our computation:
The graph
A linear equation is represented as
y - Y = m(x - X)
Where
m = Slope
(X, Y) = point on the graph
The slope is calculated using
m = (Y - y)/(X - x)
Using the points on the graph, we have
m = (5 - 2)/(0 - 1)
m = -3
Using the above as a guide, we have the following:
y - Y = -3(x - X)
Using the point (1, 2), we have
y - 2 = -3(x - 1)
Hence, the equation of the line is y - 2 = -3(x - 1)
