Okay, let me just make this a little clearer. Hopefully, this is what you meant:
A. y - 8 = -4(x + 4)
B. y - 8 = 4(x + 4)
C. y + 8 = 4(x - 4)
D. y + 8 = -4(x - 4)

This can also be written as y2 - y1 = m(x2 - x1).
Your M is your slope.
Both A and D have their m as a negative 4. Because you are looking for a positive slope, immediately cancel those answers.
* note that you could have also put them in a more standard form and discovered m which is the x in bx.
Now, you are looking for an equation that contains (4,-8).
Because it is written as y2-y1, your y's are actually points if you were to find another slope or something. This part is a bit hard to explain, but -8 is only found in the y coordinate place in answer B. Your answer would be B. For more explanation on that, there's this great site called coolmath.com and if you search for finding the equation of two points, it explains it much better on there, but I would not want to plagiarize.
The answer is B.
Answer:
15 x 6 x 8
Step-by-step explanation:
total money is cost per lawn times number of lawns per week times number of weeks
cost per lawn is $15
number of lawns per week is 6
number of weeks is 8
so cost total money is 15 x 6 x 8 which is none of them
where did the 20 and 11 come from?
25(25) = 625
625/60 ≈ 10.4166
Or when rounded to the nearest hundredth, 10.42
Total paintings = 6
Number of different places for each painting = 6
Total number of ways she could hang all the painting = 6 × 6 = 36
Answer:
b) 16 rt 2
Step-by-step explanation:
using the 45-45-90 triangle trick,
let x=16
then BC is x rt 2, or 16 rt 2
