Since the y-intercept is at (0, 0), hence the equation of the line is y = 4/3x
The equation of a line in slope-intercept form is expressed as:
y = mx + b where:
m is the slope
b is the y-intercept
Using the coordinate points (0, 0) and (3, 4)
Slope = 4-0/3-0
Slope = 4/3
Since the y-intercept is at (0, 0), hence the equation of the line is y = 4/3x
