m =  ,   (x₁ , y₁) = (-2, -4)
,   (x₁ , y₁) = (-2, -4)
y - y₁ = m(x - x₁)
y -(-4) =  (x - (-2))
(x - (-2))
y + 4 =  (x +2)
(x +2)
y + 4 =  + 1
 + 1
      y =  - 3
 - 3

Multiplication property of equality can be used to solve: 
Step-by-step explanation:
First of all, lets define the multiplication property of equality
The multiplication property of equality states that if one side of an equation is multiplied with any number the other side is also multiplied with the number.
Given equations are:

By observing the equations we can see that only third equation has a fraction in it so it has to be multiplied with -2 for solution

Hence,
Multiplication property of equality can be used to solve:

Answer:
Equilateral, acute
Step-by-step explanation:
Equilateral triangles have all sides the same length (all sides are 4 ft in this triangle, so it is equilateral).
Acute triangles have no angles that are greater than or equal to 90 degrees (all angles are 60, which is less than 90, so it is acute).
