Answer:
[tex]y=2x[/tex]
Step-by-step explanation:
Equation of a Line
Two variables x and y are linearly dependent when they are related by the equation
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept, or the value of y when x equals 0. We are given a particular equation for the line such as b=0, so we only need one point to compute m. That point is (-1,-2):
[tex]-2=m(-1)[/tex]
It follows that
[tex]m=2[/tex]
Thus the equation of the line is
[tex]\boxed{y=2x}[/tex]
