Answer:

-2

Step-by-step explanation:

find two points where they line up on the cross sections of the graph

-2, 3

-1, 1

-1 x -2 y

it goes right 1 and down 2

-2/1 or -2

Sati [7]

Answer:

Alright bear with me, this is gonna be a long one.

The Y INTERCEPT

So the y-intercept is going to be where the line intersects the Y-AXIS. The y-axis is the vertical part of the graph with the numbers on it.

So, for the first one, the line goes through the origin which means that that the y intercept is going to be (0,0)

The next one, the line intersects the y-axis at (0,1)

Here's a tip: the y-intercept will always have 0 as it's x coordinate.

The Slope

Alright, the slope of a vertical line can be found using an equation. Most typically people will describe the slope as RISE/RUN meaning how many units you move up "rise" and how many units you move horizontally "run" to touch the line. Of course, it's easier when you can identify points.

So to make this a little bit easier to understand, I will show you how to use the equation to find the slope.

$\frac{y2-y1}{x2-x1}$

So for this equation, what you need is two coordinates. So for the first graph, I'm going to use the points (0,0) and (1,3)

$\frac{3-0}{1-0}$

So we make the three y2 because it's the second y coordinate and the y1 would be 0. Same applies to the x coordinates but use the x values.

the slope for the first graph would be 3/1

FOR THE SECOND GRAPH

$\frac{y2-y1}{x2-x1}$

Here's our equation now pick two points. I'll be using (-5,4) and (0,1)

$\frac{1-4}{0-(-5)}$

Don't forget that a negative-a negative = positive

which will leave you with

$\frac{-3}{5}$

since it can't be simplified any further, your slope is -3/5.

I hope I was able to help you understand this a bit better :)

A square is inscribed in a right triangle with leg lengths 6 and 8 such that they have a common right angle. find the square's s

DaniilM [7]

The square's side length is 24/7 or 3.428 units if the square is inscribed in a right triangle with leg lengths 6 and 8 such that they have a common right angle.

<h3>What is a right-angle triangle?</h3>

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

First we have to find the line that goes through the points (0, 6) and (8, 0)

(y - 0) = (0-6)/(8-0)(x-8)

y = (-6/8)[x - 8]

Plug y = x

x = (-6/8)[x - 8]

After solving:

x = 24/7 or 3.428

y = 24/7 or 3.428

Thus, the square's side length is 24/7 or 3.428 units if the square is inscribed in a right triangle with leg lengths 6 and 8 such that they have a common right angle.

What is 234/275 in simplest form?

Alla [95]

Set up the long division.

275|234

2 Calculate 2340 ÷ 275, which is 8 with a remainder of 140.


3 Bring down 0, so that 1400 is large enough to be divided by 275.

4 Calculate 1400 ÷ 275, which is 5 with a remainder of 25.

5 Bring down 00, so that 2500 is large enough to be divided by 275.


6 Calculate 2500 ÷ 275, which is 9 with a remainder of 25.

7 Therefore, 234 divided by 275 approximately equals 0.8509
234÷275=0.8509
8 Simplify
0.8509
