We need to find which of the equations has a slope of 1/4

At first we should know that, the general form of the slope intercept form is

y = mx + b

Where m is the slope

So, we will check the options:

I. y = 1/4 x - 5

Compare to the general form

so, the slope = 1/4

II. ( y - 3.5) = 0.25 ( x - 2.75)

so,

y - 3.5 = 0.25x - 0.25 * 2.75

y = 0.25x -2.25 * 2.75 + 3.5

so, the slope = 0.25

III. 5x - 20y = 32

-20y = -5x + 32

Divide all terms by -20

y = (-5/-20) x - 32/20

y = 0.25 x - (32/20)

so, the slope = 0.25

IV. 5x + 20y = 32

20y = -5x + 32

Divide all terms by 20

y = (-5/20) + 32/20

y = -0.25 x + (32/20)

so, the slope = -0.25

As a result

The answer is option h). I , II and III only
