Inserting value of a into this equation




It should be C. the first floor is going to be 13 feet longer, so x squared +13 is going to be the first floor
Answer:
C
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (9, 3) ← 2 points on the line
m =
=
=
, thus
y =
x
Or
y =
→ C
