The linear equation of the graph is y = 1 / 2 x
How to find the linear equation to a graph?
The linear equation of the graph can be found as follows:
y = mx + b
where
Therefore,
m = y₂ - y₁ / x₂ - x₁
Hence,
(2, 1)(4, 2)
m = 2 - 1 / 4 - 2
m = 1 / 2
Hence, using (2, 1)
y = 1 / 2x + b
1 = 1 / 2(2) + b
b = 0
Therefore,
y = 1 / 2x
