Answer:
Yes, it is a function. In particular it is the equation of a line with slope 5/3 and a y intercept of -100/3
Step-by-step explanation:
Slope intercept form equation of a line is
y = mx + c
where m = slope and c = y-intercept
Comparing this general equation with the given equation gives
m = 5/3 and c = -100/3
y is the dependent variable and x the independent variable so
y = f(x) = (5/3)x - 100/3
