Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 
, thus
y = x + c ← is the partial equation
To find c substitute (- 4, - 9) into the partial equation
- 9 = - 2 + c ⇒ c = - 9 + 2 = - 7
y = x - 7 ← equation of line

She would have this amount
Answer:
No solution
Step-by-step explanation:
This is just a simple system of equations.
y=-1/4x+2
8y+2x=-40
Get the same variables onto their corresponding sides, so it will look like this:
y=-1/4x+2
8y=-2x-40
Now here, you have to be careful, because to solve for the system of equations, you need to make sure you are multiplying the equation proportionately.
8y=-2x+16
8y=-2x+40.
But here you see that they share the same variables in a similar format, but their values are supposed to be different, meaning that this equation is a false claim. So you would respond to the question as "no solution.
Answer:
The answer of your question is: y = - x + 11
Step-by-step explanation:
Data
A (3, 8)
B (9,2)
Formula
m = 
(y - y1) = m(x - x1)
Process
1.- Calculate the slope
m = 
= 
m = -1 slope
2.- Substite point A and slope in the equation
(y - 2) = - 1(x - 9)
y - 2 = -x + 9
y = -x + 9 + 2
y = - x + 11 Solve for y
