What’s the slope of (3,1200)(6,800)

Your slope is -133 1/3

Step-by-step explanation:

slope intercept form:

slope (m) = (y₂ - y₁)/(x₂ - x₁)

Let:

(x₁ , y₁) = (3 , 1200)

(x₂ , y₂) = (6 , 800)

Plug in the corresponding numbers to the corresponding variables:

m = (800 - 1200)/(6 - 3)

Simplify. Remember to follow PEMDAS. First solve the parenthesis, then divide:

m = (-400)/(3)

m = ~-133 1/3

Your slope is -133 1/3.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
