Question

Prompt

For the linear function

f

, the graph of

y = f (x)

in the

x y

-plane has a slope of

\frac{1}{3}

and passes through the point

(0, 7)

. Which equation defines

f

f (x) = \frac{1}{3} x + 7

f (x) = \frac{1}{3} x + \frac{1}{7}

f (x) = \frac{1}{3} x - \frac{7}{3}

f (x) = \frac{1}{3} x - 7
