Look at where the line crosses the X axis.
Here we see it crosses -2
So your answer is A (-2, 0)
let's firstly convert the mixed fractions to improper fractions and then multiply across.

Answer:
-19
Step-by-step explanation:
f(x)=5x+1
F(-4) - substitute -4 as the x
F(-4)=5(-4)+1
F(-4) = -20 + 1
f(-4) = -19
