What is the slope of the line that passes through (3, −7) and (−1, 1)?
Art [367]

Answer:

<h2>The answer is - 2</h2>

Step-by-step explanation:

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

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(3, −7) and (−1, 1)

The slope is

m =  \frac{1 -  - 7}{ - 1 - 3}  =  \frac{1 + 7}{ - 4}  =  -  \frac{8}{4}   =  - 2 \\

We have the final answer as

<h3>- 2</h3>

Hope this helps you

There are a total of 64 students in a drama club and a yearbook club. The drama club has 10 more students than the yearbook club
zaharov [31]

Answer:

y = 27

Step-by-step explanation:

Let d = number Of drama club members

let y = number of yearbook club members

now you can write two equations, one for the total number of students, and one for the difference between them.

d + y =64

d - y = 10

 

to solve for d, add these two lines together (so as to remove the y’s)

2d + 0y = 74

d = 37

now substitute back into one of the formulas

d+y=64

37+y=64

subtract 37 from each side,

y = 27
