The equation of the line is
y = -3/2 x
How to find the equation
The equation is solved to be in the slope intercept form
y = mx + b
Where
m = slope
b = y-intercept (the value of y when x is zero)
Using points from the graph (2, -3) and (0, 0)
slope = change in y / change in x
slope = (-3 - 0) / (2 - 0)
slope, m = -3/2
The graph passed through the origin (0, 0), hence b = 0
y = mx + b
y = -3/2 x
