PLEASE HELP ASAP!? Which equations in point-slope form are equations of the line that pass through the points (4, 5) and (−3, −1)?Choose exactly two answers that are correct.
A. y-3 = 7/6 (x-1)
B. y-5 = 6/7 (x-4)
C. y+1 = 6/7 (x +3)
D. y-4 = 7/6 (x-5)

Answer 1
Answer:
I am not sure about point slope, but I can find an equation in slope-intercept form and convert it, so
y=mx+b, m=slope
slope=(y1-y2)/(x1-x2)
we have points
(4,5)
(-3,-1)
(x,y)
x1=4
y1=5
x2=-3
y2=-1
subsitute
(5-(-1))/(4-(-3))=(5+1)/(4+3)=6/7
y=6/7+b
sybsitute and solve for b
(4,5)
x=4
y=5
5=6/7(4)+b
5=24/7+b
5=35/7
subtract 24/7 from both sides
11/7=b
y=6/7x+11/7
convert to the point slope form and find equivilent fraction
since the question asks for 2 answers that are correct and only 2 of the equations have slope of 6/7 I can guess that the answers are B and C
y=mx+b, m=slope
slope=(y1-y2)/(x1-x2)

Answer 2
Answer:
point slope form is
y -y1 = m(x - x1)
First, we need to calculate the slope.
%7D%7B4-(-3)%7D%20%3D%20%5Cfrac%7B6%7D%7B7%7D)
The slope is 6/7
Next, we plug in both points.
m = 6/7, (x1,y1) = (4,5)
The equation will be:
y - 5 = 6/7 (x - 4)
Plugging in m = 6/7, and (x1,y1) = (-3,-1)
The equation will be
y + 1 = 6/7 (x + 3)
Your answer is B and C.
y -y1 = m(x - x1)
First, we need to calculate the slope.
The slope is 6/7
Next, we plug in both points.
m = 6/7, (x1,y1) = (4,5)
The equation will be:
y - 5 = 6/7 (x - 4)
Plugging in m = 6/7, and (x1,y1) = (-3,-1)
The equation will be
y + 1 = 6/7 (x + 3)
Your answer is B and C.

15% is equivalent to the fraction 3/20 so you must divide 140 by 20 then multiply by 3 to get the final answer of 21 students. Hope this helps :D

Answers
yes you can and it is negative because if you think about it, the answer to the 3rd power is your original question, so for example, -8 would equal to the answer times itself 3 times
now ask yourself, does 2 times itself 3 times = to -8
or -2 times itself 3 times = to -8
now ask yourself, does 2 times itself 3 times = to -8
or -2 times itself 3 times = to -8
