$a = 4$ $a=4$
$b = - \frac{4}{3}$ $b=-4/3$
$d = 7$ $d=7$
$e = 2$ $e=2$

Explanation:

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

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

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

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