For this case we have that by definition, the point-slope equation of a line is given by:

We have the following points:

We chose a point:

Substituting in the equation we have:

Finally, the equation is: 
Answer:
OPTION C
Answer:
$2000
Step-by-step explanation:
let x be the money she invested
lets assume this was for 1 year
0.09(x/2) + 0.07(x/2) = 160
multiply each side by 2 to cancel the denominators:
0.09x + 0.07x = 320
0.16x = 320
x = 2000
39) y=20x+175
40) y=20(2)+175, so $215
Answer:
A
Step-by-step explanation:
This is a strict inequality so the line must be dotted, meaning it can only be A or D.
The inequality says that y is less than -2x+4 so we want the region under the line, making A the correct answer.
