Find the slope of the line passing through the points (6, -6) and (4, -4)
djyliett [7]

To find the slope (m), use the slope formula:

m=\frac{y_2-y_1}{x_2-x_1}         and plug in the two points

(4, -4) = (x₁, y₁)

(6, -6) = (x₂, y₂)

[lines usually go from left to right, so the point furthest to the left is the 1st point]

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{-6-(-4)}{6-4}   [two negative signs cancel each other out and become positive]

m=\frac{-6+4}{6-4}

m=\frac{-2}{2}

m = -1

How are the perimeters of the preimage polygon and the image polygon related? Explain.
Romashka-Z-Leto [24]

The difference between Pre-Image and Image is given as follows:

  • Image is the shape AFTER a transformation is the picture of the transformation.
  • A transformation's preimage is the shape BEFORE the change.

<h3>How do you define relationships between Image and Preimage?</h3>

Usually, the difference between image and pre-image is the way or method of transformation.

<h3>What is transformation in math?</h3>

A transformation is a broad phrase covering four distinct methods of changing the shape and/or location of a point, line, or geometric figure.

The Pre-Image is the original shape of the item, and the Image during the transformation is the final shape and location of the object.

The types of transformation in math are;

  • translation
  • rotation
  • reflection, and
  • dilation.

Ryan is rowing a small boat out to and back from an island 20 miles away at a rate of
Misha Larkins [42]

Answer:

The speed with which Ryan was rowing was 4 mph

Step-by-step explanation:

With a small boat, Ryan wants to row towards an island and come back at a speed of x mph and the island is 20 miles away from him.  

Therefore, total 20 + 20 = 40 miles he rowed for 5 hours.

On the way to the island, there was a wind of 4 mph in the direction of his motion and on the way back also there was a wind of 4 mph in the direction of his motion.

So, in the total journey, he has a speed of (x + 4) mph.

Therefore, \frac{40}{5} = x + 4

⇒ x + 4 = 8

⇒ x = 4 mph.

Therefore, the speed with which Ryan was rowing was 4 mph. (Answer)
