The equation of the given line is y = 2x
Equation of a line
The standard equation of a line is y = mx + b
- m is the slope
- b is the y-intercept
From the graph, we can use the coordinate point (1, 2) and (2, 4)
Get the slope
m = 4-2/2-1
m = 2/1
m = 2
Since the line pass through the origin, hence b = 0
Get the required equation:
y = 2x + 0
y = 2x
Hence the equation of the given line is y = 2x
