We'll have to get this into a y=m*x+by=mx+b form

Explanation:

Subtract 22 from both sides:
->y+cancel2-cancel2=1/4(x-1)-2

Now, lose the brackets:
->y=1/4x-1/4-2
Or:
->y=1/4x-2 1/4

Where 1/4 is the slope and (0,-2 1/4) is the y-intercept

Slope: 1/4 color(white)("XXXXXX")y-intecept: (-2 1/4)

Explanation:

Remember that the general slope-intercept form is
color(white)("XXX")y=color(green)(m)x+color(blue)(b)
with slope of color(green)(m) and y-intercept of color(blue)(b)

Given
color(white)("XXX")y+2=1/4(x-1)
we wish to convert this into slope-intercept form.

color(white)("XXX")y+2 =1/4x-1/4

color(white)("XXX")y=color(green)(1/4)x + (color(blue)( - 2 1/4))

So this line has a slope of color(green)(1/4)
and a y-intercept of color(blue)(""(- 2 1/4))
