Question

the slope of a line is -1/5 and the y-intercept is 5

Answer 1

The equation of a line is:
y = -x/5 + 5

or

x + 5y = 25

Answer 2

With the information above, we can make a slope-intercept form. In it's general form it looks like this: y = mx + b

Where m is the slope and b is the y-intercept.

So, constructing the equation will be easy.

So, the answer to the question is y = -(1/5) + 5.
