Answer:20 milkshakes
Step-by-step explanation: 80 x 25% =20
25% or 1/4 of 80 is 20 if that makes sense to you.
Answer:
<u>Step-by-step explanation:</u>
Use the Slope formula: 
and the Point-Slope formula: y - y₁ = m(x - x₁)
a) (-2, 0) and (3, 4)

Let (x₁, y₁) = (-2, 0)
y - y₁ = m(x - x₁)

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

First, combine like terms.
3y+3x>-6x+12
Next, because there can not be the same variable on both sides, add 6x to both sides.
3y+9x>12
The slope is -9y because it has the variable and b= 90
