Find the slope of each line

Mathematics
1 answer:
sladkih [1.3K]3 years ago
3 0

Step-by-step explanation:

To find the Slope of each line, pick two points you can clearly identify on each graph. The first graph has a point (-5,5) and (4,-5). Using these two points find the difference of the y coordinates divided by the difference in the x coordinates, like this:

5 - (-5). = 10

-5 - 4 = - 9

So the Slope is - 10/9

Same steps for all. Your equation is

(y1 - y2) / (x1 - x2)

Answer:

10 sides (decagon)

Step-by-step explanation:

You find the perimeter by adding up all the sides of a shape.

side + side + side + side... = perimeter

You know that <em>each</em> side is 4/5 centimeters. You also know that the perimeter is 8 centimeters.

<u>You can set up an equation like this:</u>

4/5 * number of sides = 8

<em>or you can write it in a simpler form as:</em>

4/5x=8

<u>Now solve it like a normal equation:</u>

5 * (4/5x) = (8) * 5

(4x) / 4=(40) / 4

x = 10

So, you know the shape has 10 sides that are 4/5 centimeters each.

The smaller triangle is the image of the larger triangle after a dilation. The center of the dilation is (4,2). What is the scal
zzz [600]
Small triangle: <span>The side // x axis has a length of 4
Large triangle: The side // x axis has a length of 12

So Small/Large = 4/12 = 1/3

Small triangle: <span>The side // y axis has a length of 3
Large triangle: The side // y axis has a length of 9


</span><span>So Small/Large = 3/9 = 1/3

So the scale factor to obtain this dilatation is 1/3</span>
