Given
The equation in terms of a is

Hey there! :)
We're given the points : (4, 8) & (8, 11)
Plug these into the slope equation, which is : m = (y₂-y₁) / (x₂-x₁)
m = (11 - 8) / (8 - 4)
Simplify.
m = 3/4
So, our slope is 3/4!

Answer:
y < -9
Step-by-step explanation:
y + 13 < 4
Subtract 13 from each side
y + 13-13 < 4-13
y < -9
