Equation in point-slope form is 
Option C is correct.
Step-by-step explanation:
We need to Write an equation in point-slope form for the line through the given point with the given slope. (-7,9); m=4/5
The formula used for point-slope form is:

We are given slope m = 4/5
Point (-7,9) where x₁ = -7 and y₁ = 9
Putting values in the formula:

So, equation in point-slope form is 
Option C is correct.

Step-by-step explanation:
y=3x
so
3x=-x+4
3x+x=4
4x=4
x=1
so
y=3(1)
y=3

Answer:
the answer is A
Step-by-step explanation:
She needs to earn at least 84 to buy the mp3 player
earnings=earningsperhour times numberofhoursworked
earnings per hour=12 dollars
number of hoursworked=h
therefor
earnings=12 ties h or12h
earnings is at least 84
earnings is greater than or equal to 84
earnings<u>></u>84
12h<u>></u>84
solve
12h<u>></u>84
divide both sides by 12
h<u>></u>7
she needs to work at least 7 hours
