Question

Construct a function with a rate of change of 1/3 and an initial value of -3.

(put your equation in slope-intercept form y = mx +b)

Answer 1

y = x/3 - 3

Explanation:

x/3 is the equivalent of 1/3(x)

Answer 2

So you pretty much have all you need. 1/3 represents slope, and slope is m. Initial value would be your y intercept which is b.

y=1/3x-3
