#a=4#
#b=-4/3#
#d=7#
#e=2#

Explanation:

Start with a. a is the y-value, so set y equal to a and x equal to 0.
#a=3(0)+4# #rarr# expand
#a=0+4# #rarr# simplify
#a=4#

Repeat this for b, but with x equal to b and y equal to 0.
#0=3(b)+4# #rarr# subtract 4 from both sides
#-4=3b# #rarr# multiply by #1/3#
#-4/3=b#

Again for d, with 1 as your x-value and d as the y-value.
#d=3(1)+4# #rarr# expand
#d=3+4# #rarr# simplify
#d=7#

Finally, repeat for e, with the x-value as e and your y-value as 10.
#10=3(e)+4# #rarr# subtract 4 from both sides
#6=3e# #rarr# multiply by #1/3#
#2=e#
