Answer:
y = (1/3)x +5/3
Step-by-step explanation:
The general equation of a line is
y = mx+b
where m is the slope and b the y-intercept
Since the slope is 1/3 we have
y = (1/3)x +b
since the line passes through (x,y) = (-2,1) this point satisfies the equation
1 = (1/3)(-2) + b ===> b = 1+2/3 ===> b = 5/3
and the equation of the line is
y = (1/3)x +5/3
