Answer:

#y-#intercept #=4#

#x-#intercept #=-1#

Explanation:

#y=4x+4#

For finding #y#-intercept , put x = 0.

#y=4(0)+4#

#y=4#

For finding #x#-intercept , put y = 0.

#0=4x+4#

#-4=4x#

#-1=x#

Answer:

#-1" and "4#

Explanation:

#"to find the intercepts, that is where the graph crosses"#
#"the x and y axes"#

#• " let x = 0, in the equation for y-intercept"#

#• " let y = 0, in the equation for x-intercept"#
