To find the x intercept set y=0 and solve for x.
To find the y intercept set x=0 and solve for y.

Explanation:

x-intercept
y=4x+4
with y=0 becomes
color(white)("XXXX")0=4x+4
color(white)("XXXX")x= -1

y-intercept
y=4x+4
with x=0 becomes
color(white)("XXXX")y = 4(0) +4
color(white)("XXXX")y = 4

x-intercept is (-1)
y-intercept is 4
