Question

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

Point slope form is 

y -y1 = m(x - x1)

First, we need to calculate the slope.

$Slope = \frac{y_2-y_1}{x_2-x_1} = \frac{5-(-1)}{4-(-3)} = \frac{6}{7}$

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.

Answer 2

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
