Answer:
Step-by-step explanation:
1.
(-2,0) (0,-7) y2-y1
-----------------
x2-x1
-7-0= -7
0- (-2)= 2 ------>>> -7/2 =m or slope
2.
y= -7/2x+b to find b u plug in one pair of coordinates for example (-2,0)
and use inverse properties to find b
0 = -7/2(-2) + b
14/2 = 7
0= 7+b
-7 -7
-----------
-7=b
3.
y=-7/2x-7
Answer:
k=3
Step-by-step explanation:
+ we note f(p)= 
+ Because of "p-1 is a factor of f(p)", that means f(p)= (p-1)* g(p)
Then we have f(1)= (1-1)*g(1)= 0* g(1)= 0
+ We replace p=1 in f(p) and we have:
f(1)=0
that means: 
then 1+1+1-k = 0, 3-k=0 or k=3
Hope that useful for you.
The correct answer is letter C
Answer:
k equals negative StartFraction 2 Over 3 EndFraction
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
we have that
For x=-3, y=2
Find the value of the constant of proportionality k

substitute the value of y and x

The linear equation is

therefore
k equals negative StartFraction 2 Over 3 EndFraction
