What is the slope of the line ?

Marat540 [252]

Answer:

3/4

Step-by-step explanation:

You can calculate slope with $\frac{y1-y2}{x1-x2}$

2 points from the graph are (0,-1) and (4,2)

plugging the points in would give you

$\frac{2-(-1)}{4-0} = \frac{3}{4}$

Please rate me as brainliest if this helped!

Write an equation of the line that passes through the point (–1, 4) with slope 2. A. y+1=−2(x−4) B. y+1=2(x−4) C. y−4=2(x+1) D.

In-s [12.5K]

Answer:

$y-4=2\,(x+1)$

which agrees with answer C in your list of possible answers.

Step-by-step explanation:

We can use the general point-slope form of a line of slope m and going through the point $(x_0, y_0)$ :

$y-y_0=m(x-x_0)$

which in our case, given the info on the slope (2) and the point (-1, 4) becomes:

$y-y_0=m\,(x-x_0)\\y-4=2\,(x-(-1))\\y-4=2\,(x+1)$

Tatiana's book has an area of 88 square inches. what are the length and wide measurements of the book

Vedmedyk [2.9K]

A= l•w

So you can make it in any way! The one I got is 44•4 because

A= l•w
A= 4•22
A= 88

So I guess it depends on the way you want it as long as it equals 88 as long as you length and width are multiplied to make the 88, if you host what I mean!

PLEASE HELP!!!! Find the value of -7 - 8 - (-8) - 7. 0 14 -14 -30

miskamm [114]

-7 - 8 - (-8) - 7 × 0(14) - 14 - 30

(I think that's what that says)

Do PEMDAS

0(14) = 0

-7 × 0 = 0

You're left with -7 - 8 - (-8) - 14 - 30

Go from left to right

-7 - 8 = -15

-15 - (-8) = -7

-7 - 14 = -21

-21 - 30 = -51
