What is the slope of a trend line that passes through the points (1,3) and (10,25)

22/9

Step-by-step explanation:

The slope of a line can be found by using the slope formula

.

Or what I like to do is line up the points and subtract vertically, then put 2nd difference over 1st difference. Like so:

 ( 10  , 25)

- (  1  ,    3)

----------------

9         22

So the slope is 22/9.

You could have done it the other way too. That is:

 (1  ,  3)

-(10 , 25)

------------

-9    -22

So the slope is -22/-9 or just 22/9.

The slope of a trend line is:

Step-by-step explanation:

The slope m of a line is calculated using the following formula:

For any pair of points that belong to the line

In this case the points are (1,3) and (10,25)

Therefore the slope is:

for the points

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
