slope: (-8)(8)
y-intercept: 44

Explanation:

Any equation in the form:
color(white)("XXX")y=color(red)(m)x+color(blue)(b)XXXy=mx+b
is in a form called the "slope intercept form" with a slope of color(red)(m)m and a y-intercept of color(blue)(b)b

y=color(red)(-8)x+color(blue)(4)y=8x+4 is in this form
with slope color(red)(m=-8)m=8 and y-intercept color(blue)(b=4)b=4
