#y#-intercept is #-4#

And for every #x#-value there would be an increase of #3# in the #y# value

Explanation:

Choose #x# values and work out the #y# values.

#x rarr y#
#0, -4#
#1, -1#
#2, 2#
#3, 5#
#4, 8#
#5, 11#
#6, 14#
#7, 17#
#8, 20#
#9, 23#
#10, 26#

Now plot the points and join them with a straight line.

Whenever there's an increase in the #x# by #1#,. there will be an increase in #y# by #3.#
graph{y=3x-4 [-10, 10, -5.21, 5.21]}
