The formula of a slope:

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

We have the points (4, 1) and (2, 5). Substitute:

m=\dfrac{5-1}{2-4}=\dfrac{4}{-2}=-2

<h3>Answer: The slope is -2.</h3>

Hello!

Explanation:

Slope-intercept form: → y=mx+b

m: represents the slope and is constant.

b: represents the y-intercept.

Rise/run

\frac{rise}{run}

m=\frac{y^2-y^1}{x^2-x^1}

x^1,y^1=(4,1)

x^2,y^2=(2,5)

\frac{5-1=4}{2-4=-2}=-2

So the final answer is \boxed{=-2}

Hope this helps!

Thank you :)

Solve for x. Round answer to the nearest tenth (0.1).
ICE Princess25 [194]

Answer:

x = 9.9

Step-by-step explanation:

This is a isosceles triangle, with sides measurements (1 , 1 , √2), and the angles being (45° - 45° - 90°). Note that the side measurements of 1 is opposite of that of a 45°, while the measurement of √2 is opposite of that of 90°.

In this case, multiply. The side measurement of 1 has 7.

1 x 7 = 7

In the same, you must multiply 7 with √2

x = 7 * √2 = 7√2.

√2 = ~1.414

7 x 1.414 = 9.898

Round to the nearest tenth:

9.898 rounded to the nearest tenth = 9.9

x = 9.9

Lila evaluates the expression using the following steps:(−7.13+63.97)+(−54.8−3.4)−71.1+(−58.2)−129.3Describe the error that Lila
mihalych1998 [28]

Lila's error was that she added -7.13 to 63.97 to get -71.1

Lila steps are as folows

(−7.13 + 63.97) + (−54.8 − 3.4) = −71.1 + (−58.2) = −129.3

In the first bracket, Lila was suppose to subtract 7.31 from 63.97 since there is a negative in front of 7.31.

So, the correct expression should be

(−7.13 + 63.97) + (−54.8 − 3.4) = 56.84 + (−58.2) = 56.84 - 58.2 = −1.36

So, Lila's error was that she added -7.13 to 63.97 to get -71.1
