The equation of the line could be given by: y = 3x.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
In this problem, the lines goes only through quadrants III and I, which means that:
- The line is increasing, which means that the slope is of m > 0.
- The y-intercept is of b = 0.
Hence, researching the options on the internet, the line is:
y = 3x.
