6 0

Answer:

y=2x-3

Step-by-step explanation:

Y-intercept can be read off the graph.

Slope can be determined using the formula:

y2-y1 divided by x2-x1 (Substitute co-ordinates)

Answer:

y=2x-3

Step-by-step explanation:

y=mx+b

Where m is the slope and b is the y intercept

Slope is rise over run, the line is up 2 over 1

And the point of the line where it meets the y axis is -3. so b is -3

Draw a line representing the “rise” and a line representing the “run” of the line. State the slope of the line in simplest form.
Oksanka [162]

The slope of the line in its simplest form is 3.

The slope of a line is Slope=\frac{Rise}{Run}.

We need to find the slope of the line in its simplest form.

<h3>What is the slope?</h3>

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope is often denoted by the letter m; there is no clear answer to the question of why the letter m is used for slope.

Select any two points on the line like A and B.

From the below figure it is clear that

Rise = Change in y = -2-(-5) = 3

Run = Change in x = 9-0 = 9

Now, \frac{9}{3} =3

Therefore, the slope of the line in simplest form is 3.

After distributing the terms (3x - 7) (2x + 5), you get a new expression of the form
jeka57 [31]
First multiply (3x-7) and (2x+5)
i already did the multiplication so i am writing the answer
(3x-7)(2x+5)
6x^2+x-35

a is 6
b is 1
c is -35

if you want me to share how i did the multiplication then do let me know

Pls pls help <br> Perform the indicated operations.<br> a) 7a/20b<br> b) 7ab/20<br> c) 7/20ab
Elina [12.6K]

Answer:

it's a) 7a/20b

Step-by-step explanation:

5( \frac{a + 2}{4b} ) - 2( \frac{a - 1}{10b} ) + 4( \frac{a - 3}{5b} ) \\  \\  \frac{5a + 10 - 2a + 2 + 4a - 12}{20b }  \\  \\  \\  \frac{7a}{20b}

Find the distance between the points.<br> (r, s) and (0, 0)
zhenek [66]

Answer:  \sqrt{r^2+s^2

=====================================================

Reason:

Plot the points (0,0) and (r,s). You can place (r,s) anywhere you want.

Connect the two points mentioned and form a right triangle such that the segment from (0,0) to (r,s) is the hypotenuse of said right triangle.

The horizontal leg has a length of r-0 = r units, while the vertical leg will be 's' units.

Check out the diagram below.

We then apply the pythagorean theorem to say r^2+s^2 = h^2 where h is the hypotenuse. Solving for h gets us h = \sqrt{r^2+s^2}. We only focus on the positive square root since a negative hypotenuse makes no sense.

Since we made the hypotenuse the segment with endpoints (r,s) and (0,0), this means the hypotenuse length and the distance are the same thing.

Therefore, the distance from (r,s) to (0,0) is \sqrt{r^2+s^2}

As an alternative, you can use the distance formula to get the same answer. The distance formula is effectively the pythagorean theorem phrased a different way.
