Answer:
I. y = x +5
Step-by-step explanation:
You want to know which equation represents a smaller rate of change:
I. y = x + 5
II. y = 3x - 2
Each equation is written in "slope-intercept form", y = mx +b.
In this form, the rate of change (slope) is the coefficient of x. It tells the number of vertical units of change corresponding to each horizontal unit of change.
Equation I has a rate of change of 1.
Equation II has a rate of change of 3.
Function I has the lesser rate of change.

Additional comment
For a question like this one, we're generally concerned with the magnitude of the rate of change.
For example, function I with a slope of 1 will be considered to have a lesser rate of change than a function such as y = -3x +6 with a slope of -3, even though -3 is less than 1 on a number line.
