m=4, therefore your slope is 4.

Steps:

m=y2-y1/x2-x1

Substitute values in:

m= 9-(-7)/3-(-1)

Then just simplify. :)

Hope this helps. :)

Answer:

m=4

Step-by-step explanation:

m = change in y/change in x

m = 9-(-7) / 3-)-1)

m= 16 / 4

m = 4 (slope)

Answer:

so to get a third you divide it by 3

first convert it to fraction

so it is 26/3

so do 26/3 divided by 3

so we do keep switch flip

26/3*1/3

so answer is 26/9 or 2 8/9

Which equation represents the line that passes through the points (-5,2) and (9,0)

V125BC [204]

Step-by-step explanation:

Given points 

( -5 , 2) and (9 , 0)

First calculating slope(m)

= ( y2 - y1) / ( x2 - x1) 

= ( 0-2) / ( 9+5)

= -2 / 14

= -1/7

Now The equation of line is given by 

y - y1 = m ( x - x1) 

y -2 = -1/7 (x + 5)

7( y - 2) = -1(x + 5)

7y - 14 = -x -5

x + 7y -14 +5 = 0

x + 7y - 9 = 0 

Which is the required equation

In a four year period, about 80,000 acres of coastal wetlands in the United States are lost each year. What integer represents t

klemol [59]

Answer:

-320000

Step-by-step explanation:

Given

Lost Land = 80,000 acres yearly

Duration 4 years

Required

The total change

Represent the total change with y;

y is calculated as thus;

$y = Lost\ Land * Duration$

$y = -80,000 acres * 4$

$y = -320000\ acres$

Hence, a total of 320000 acres were lost during the period
