The calculated equation of the line is y = -7/4x + 7
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 = mx + c
Where
c = y when x = 0
Using the above as a guide, we have the following:
y = mx + 7
Using the points on the graph, we have
4m + 7 = 0
Evaluate
m = -7/4
So, we have
y = -7/4x + 7
Hence, the equation is y = -7/4x + 7
