Answer:
y + 1 =
(x + 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - y₁ = m(x - x₁)
where m is the slope and (x₁, y₁ ) a point on the line
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 2, - 1 ) and (x₂, y₂ ) = (2, 1 )
m =
=
=
=
and (x₁, y₁ ) = (- 2, - 1 ) , then
y - (- 1) =
(x - (- 2) ) , that is
y + 1 =
(x + 2)
The answer is D. He has to buy less than or equal to 4 masks
2 pounds ---- 100%
x pounds -----18%
x=(2*18)/100=36/100=0.36 pounds
