Answer:   (2,4) and (5,1) → Negative slope

(-7,8) and (-7,0) → Undefined slope

(3,5) and (-1,2) → Positive slope

(6,-3) and (-4,-3)  → Zero slope

Step-by-step explanation:

We know that the slope of a line passing through points (a,b) and (c,d) is given by :-

m=\dfrac{d-b}{c-a}

The slope of a line passing through points (2,4) and (5,1) is given by :-

m=\dfrac{1-4}{5-2}=\dfrac{-3}{3}=-1

⇒ Negative slope

The slope of a line passing through points (-7,8) and (-7,0) is given by :-

m=\dfrac{0-8}{-7-(-7)}=\dfrac{-8}{0}

⇒ Undefined slope

The slope of a line passing through points (3,5) and (-1,2) is given by :-

m=\dfrac{2-5}{-1-5}=\dfrac{-3}{-6}=\dfrac{1}{2}

⇒ Positive slope

The slope of a line passing through points (6,-3) and (-4,-3) is given by :-

m=\dfrac{-3-(-3)}{-4-6}=\dfrac{0}{-10}=0

⇒ Zero slope

There are approximately 15 milliliters (mL) in 1 tablespoon (tbsp). Which expression can be used to find the approximate number
Greeley [361]
We develop the ratio between the number of milliliters present in 1 tablespoon and that is,
                               15 mL: 1 tablespoon
We let x be the number of millileter in 3 tbsp and it can be determined through the equation below.
                                x = 3 tbsp x (15 mL/ 1 tbsp) = 45 mL
Therefore, there are 45 mL in 3 tbsp.

I only need help with #10 :) offering 10 pts
Semenov [28]

Answer:

The length of one side of the square is 3.

Step-by-step explanation:

The perimeter of any given shape is all of the sides added together. So, the perimeter of the triangle is 5x + 4x + 3x. Added together, 12x.

The perimeter of the square is (x + 2)*4. Distributed, it's 4x + 8. Since we know they're equal, set it up like this:

12x = 4x + 8

You then find that x = 1. Plug that into one side of the square, x + 2, to get 3.
