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
