Hello there!
By a over 6, I assume you mean a / 6? And by the wording, I assume 3 is outside of the fraction.
For the three outside the fraction,
(a / 6) + 3
(48 / 6) + 3
8 + 3
= 11

Answer:
y = -1/2x - 3
Step-by-step explanation:
slope: (y2-y1) / (x2-x1)
(-5 - -2) / (4 - -2)
(-5 + 2) / (4 + 2)
-3 / 6
- 1 / 2
y-intercept: y = mx + b
-5 = -1/2(4) + b
-5 = -2 + b
-3 = b
