Answer:
The answer to your question is AC = 9.9
Step-by-step explanation:
To solve this problem use trigonometric functions. The trigonometric function that relates the hypotenuse and the adjacent side is cosine.
cos α = 
Solve for hypotenuse

Substitution
hypotenuse = 
Simplification and result
hypotenuse = 9.85
slope intercept form is just solve for y
y+16=3(x-0)
y+16=3(x)
y+16=3x
mius 16 both sides
y=3x-16
3rd option
Answer:
graph{3x [-10, 10, -5, 5]}
Explanation:
this function is in the form of
y
=
m
x
+
q
with
m
=
3
,
q
=
0
so it's an straight line: ascending [
m
>
0
], that touch the
y
axis in the point
(
0
,
0
)
[
q
=
0
]
