Aline has a slope of $-7$ and contains the point $(3,0)$. the equation of this line can be written in the form $y = mx+b$. what is the value of $m+b$?

  14

Step-by-step explanation:

In point-slope form, the equation with slope -7 through point (3, 0) can be written ...

  y = -7(x -3) +0

  y = -7x +21 . . . . . eliminate parentheses

Here, we can see m=-7 and b=21, so ...

  m+b = -7+21 = 14

i am sorry it just submitted an answer but the answer is 365 boys. hopes this

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
