Answer:
y - 9 = -14 (x + 2)
Step-by-step explanation:
Point-slope form --> y - y1 = m ( x - x1)
slope = -14
y1 = 9
x1 = -2
Let's put the values all together:
y - 9 = -14 (x - - 2)
y - 9 = -14 (x + 2) ---> final answer
Answer:
y = -2x - 2
Plug the x- and y-values into the appropriate spaces in the slope-intercept form and see which value for b would make the equation true:
4 = -2(-3) +/- ?
4 = 6 - 2
4 = 4
I don't know if this makes sense, I'm sorry if it doesn't but the answer is correct because it goes through the point (-3,4)
Answer:
6
Step-by-step explanation:
Slope intercept form is y=mx+b, with m being the slope and be being the y intercept, so when you look for what b is in the equation for y=-3x+6 then 6 is b.
In case A, as the error would be a difference of 1, the assumption could be mantained, but in case B the difference will be bigger, showing that the ratio is not 3:1 but 4:1.
<h3><u>Ratios</u></h3>
Given that a preliminary study was carried out to test the hypothesis that the ratio of white to dark herons on the island was 3:1, but A) a small census found 16 white morphs and 4 dark, to determine if the assumption of a 3 :1 ratio could be rejected, and B) to determine the same question if the census were larger with 160 white morphs and 40 dark, the following calculations must be made:
A)
- 3 + 1 = 4
- 16 + 4 = 20
- 4 = 20
- 3 = X
- 60 / 4 = X
- 15 = X
- Therefore, as the error would be a difference of 1, the assumption could be mantained.
B)
- 3 + 1 = 4
- 160 + 40 = 200
- 150 = 3:1
- In this case, the difference will be bigger, showing that the ratio is not 3:1 but 4:1.
