The equation of the line in the graph is
A. y = -2/3 x + 2
How to find the equation of the line
The equation of the line will be modelled in the form
y = mx + c
where
m is slope
c is the y-intercept
The slope, m is calculated using the points on the graph (0, 2) and (3, 0)
m = (y₀ - y₁) / (x₀ - x₁)
m = (2 - 0) / (0 - 3)
m = 2 / -3
m = -2/3
c = y intercept, from the graph
c = 2
The equation of the line is y = -2/3 x + 2
