#y= 4x+3#

The standard slope intercept form of any line is

#y=mx +b#

In this case #m=4#,

hence equation would be

#y =4x+b#.

Since this line passes through #(-1,-1)#,
Plug in #x= -1# and #y= -1#
This would give

#-1= -4+b.#

Add #4# on both sides and get

#b= 3#

The required equation would be

#y= 4x+3#.
